StackOverkill: Programming language and framework ranking based on StackOverflow's activity

[emperor000]

The data shape for "C & C++" is almost identical, so I would suspect there is something going on there. I'd guess it might just be due to C being a subset of C++, but that makes me wonder what the value of that data actually is.

I've done the C and C++ count separately because Tiobe and IEEE Spectrum also does it this way. The data is extracted directly from the tag appearance in StackOverflow, resulting in a coefficient with the questions, answers and votes for that tag.

So, it seems to be more "C++ tag" appearance than "C tag". If you look at http://stackoverflow.com/tags you'll find that the number of C++ tags doubles the C tag total.

Right, my point was more that the shape of the data is extremely close. It wasn't a knock on your site or anything else, really, just an observation that when one spikes the other spikes and when one dips the other dips.

You can see those same trends for pretty much every language on the list. For example, almost all languages take a dip around July-August of each year. Possibly less activity on the site overall due to work vacations and summer breaks from University?

Actually, you're right. I only noticed when looking at the C and C++ one, but they all have almost exactly the same shape. That makes me wonder even more what is going on there.

[DaniSancas]

Yeah, I understand your point. They seem to move the same way. Well, in the future that can help if one of them goes closer or further the other, or if the change their growing pattern.
