Who tweets about xkcd?

People who read xkcd AND have twitter AND feel compelled to tweet about xkcd.
I suspect that's a small subset of the total people that read xkcd.
>Who reads xkcd?... In the process, we've scraped 20,000+ xkcd tweets
>Although Twitter doesn't contain gender data for tweeters, we were able to identify the gender of each user by their first name.
>We again applied fuzzy string matching to match a reference set of time zones/countries/continents to each tweeter's self-reported time zone.
>We had to make one critical assumption here - namely, that people will tweet shortly after reading.
>We measured this on Twitter by defining: Popularity = # of Followers Likability Ratio = # Followers / # Following
The likability one takes the cake though. Celebrities would be popular and likable. So would people who bought fake followers. People who like to follow a lot would be unlikeable.
Also it would have been interesting to compare some of these charts to the overall sample set of Twitter, considering that it also skews more towards "geek", "student", "developer" as well.
I also personally don't find the formula of 'ha ha some science reference I know of!' or graphs in comic form to be humorous.
What about female followers?
It isn't accurate to extrapolate data from such a specific group to the whole.

You could say that the people who tweet about xkcd are not a representative sample of the people who read xkcd. However, I don't see this as something absolutely intuitive -- my intuition is that it's a slightly distorted sample, but should not be _that_ off. I don't see why the people who tweet should have different characteristics to the people who read.
The thread is full of comments complaining about why the OP took this particular set -- I don't have too much problem with it. It's a sample, and quite a large one.
That a sample drawn from a group distinct within the target universe by a common factor (as "people who tweet XKCD comics" is within the universe of "people who read XKCD comics") is otherwise representative of the target group is a point which must be justified when using analysis of the sample group to draw conclusions about the target group, not something to be assumed unless there is evidence to reject it.
Because the distinction is, in and of itself, a manner in which the sample group is not representative of the target group.
