I just thought I spell this out. Pencil Revolution and Pencil Talk have nearly the same number of posts.

If the post frequency of both blogs will remain the same as in the last few weeks then Pencil Revolution will soon overtake Pencil Talk in terms of blog posts published – probably this Summer

As always in this series: if the blog owner(s) contact(s) me and objects I will take this post about their pencil blog(s) offline, so there is a chance that some of these stats posts won’t stay.

To simplify the data collection the cut off point for this blog post was the end of the first quarter 2018.

Welcome to the next post in our Pencil Blog Stats series. This time we’re adding what is probably the second oldest English-language pencil blog into the mix: Pencil Talk.

The other Pencil Talk

The official address is http://www.penciltalk.org/. I am mentioning this because for many years there was also http://www.penciltalk.com, which I think belongs or belonged to a school teacher. At some stage visitors got a warning about malicious code on that web site when trying to load the web site in their browser, but these days you just get a 403 and 404 error.

The Numbers

OK, let’s look at the number of blog posts over time.

The horizontal axis shows time (the more left, the longer ago), the vertical axis shows blog posts (starting with 0 at the bottom, reaching more than 600 blog posts near the top).

Pencil Talk’s first blog post was end of 2005. If we look at the blog posts over time there seem to be five distinct phases.

Phase A – Off to a good Start

At the end of 2005 Pencil Talk is off to a good and consistent start. The number of blog posts grows steadily.

Phase B – The Spurt

Then, in the Summer of 2007, we have the beginning of Pencil Talk’s spurt. We’ll see later that this spurt is matched in strength by the blog we looked at previously, but that the length of Pencil Talk’s spurt, from the Summer of 2007 to the end of 2010 / beginning of 2011 is unmatched.

Phase C – The Slow Down

Between the beginning of 2011 and Autumn 2014, we have the slow down where new blog posts became more and more scarce.

Phase D – The Big Empty

The blog was then taken offline in Autumn 2014 and was only put back online two years later. I was running a mirror for a day, but took it offline at the request of Pencil Talk, so access to the Pencil Talk content was only possible via the archive.org web site.

Phase E – A New Hope

Yay, Pencil Talk is back online. We’re all so happy.

Throw the Talk in the Mix

When comparing Pencil Talk with Pencil Revolution it’s becoming clear how enormous Pencil Talk’s spurt (Phase B) actually was. The gradient is similar to Pencil Revolution’s most productive periods, but it lasted more than three years. During this spurt, in Spring of 2008 Pencil Talk overtook Pencil Revolution in terms of the number of blog posts.

Awards, Awards, Awards…

I am happy to announce that

Pencil Revolution deserves the Golden Pencil Case for being the oldest pencil blog and that

Pencil Talk deserves the Golden Pencil for having most posts.

In case you wonder. Both awards are purely virtual. (Bleistift.blog is a free blog without advertising, after all).

Coming soon: How does the word count compare?

As always in this series: if the blog owner contacts me and objects I will take this post about their pencil blog offline, so there is a chance that some of these stats posts won’t stay.

To simplify the data collection the cut off point for this blog post was the end of the first quarter 2018.

Work is keeping me busy, so there haven’t been many blog posts recently. To prove that I’m still alive here’s just a quick add-on to my first blog post in my Pencil Blog Series.

Let’s have a quick look at the word count ^{[1]}I guess it’s not always clear what counts as a word and what doesn’t, so your word count might vary. of Pencil Revolution blog posts over time.

Let’s have a look at the word count plot. The x-axis (horizontal axis) is used for the dates of the blog posts. The y-axis (vertical axis) is for the word counts of the blog posts.

Each dot represents a blog post. Early posts are on the left, recent posts are on the right. Short posts are near the bottom, long posts are higher up.

The black line is a straight linear regression line. The blue curve is a LOESS (local regression) curve, which is a bit more ‘flexible’ than the straight line. You can see that in the first years, posts got longer and longer, while in recent years posts got shorter and shorter.

Cumulative Word Count

Looking at the cumulative word count we see that all Pencil Revolution blog posts together reached a word count of nearly 170,000 by now.

In this chart, the solid line shows the number of cumulative blog posts, as seen in the previous blog post, while the dotted line shows the cumulative word count. The average word count per post is 266, both lines are aligned accordingly. You can see that up to 2011 the posts were longer than the current word count average, while the posts since 2016 have been shorter than the current word count average.

That’s it for now like I said – just a quick blog post to show I’m still here. I hope to post more once work is less busy.

No, I’m not talking about the song by Schradinova.

A New Series

I’m talking about Johnny’s pencil blog – because this is another one of those R / statistics blog posts – as threatened previously. I actually started to work on this in 2015. Originally I wanted to present all the data in one blog post, but because there are old pencil blogs disappearing and new ones appearing regularly this somehow hasn’t worked out yet.

That’s why I’ve now decided to switch to looking at the pencil blogs one by one, always adding to the previous stats and since I haven’t yet figured out a better way of ordering them I decided to start chronologically. The thing is, though, if pencil shops have been around for decades, there may be older pencil blogs I’m not aware of. If you know of any pencil blogs please let me know in the comments, so that I can add it to my list of blogs to be covered. At the moment I have around 30 pencil blogs on my list. Some of the next blogs to be covered will be Pencil Talk, Dave’s Mechanical Pencils and Lexikaliker.

I decided to stick with pencil related blogs, but if there is any interest (usually there isn’t much interest in the statistics related blog posts here) I’m happy to expand to more general stationery blogs.

Also, if the blog owner contacts me to object I will take the blog post about their blog offline, so there is a chance that these stats posts won’t stay.

Pencil Revolution

Here’s the first plot about the oldest pencil blog I know: Pencil Revolution. If there are no objections from Johnny other stats about Pencil Revolution will follow soon.

So far there have been 635 blog posts on Pencil Revolution. Congratulations!

The plot above shows the blog posts over time. Horizontal lines are an indication for periods of inactivity while ‘more vertical’ lines show periods with many blog posts. In the case of Pencil Revolution, you can see that Johnny stopped revolutionising between the Summer of 2006 and the Summer 2010 and between Spring 2011 and Spring 2012 before picking up again. The latest spurt started in the Summer of 2017. I won’t comment further as the graph is fairly straightforward.

Congratulations on more than ten years and more than 600 blog posts.
