And?
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.

However, I don't see this as something absolutely intuitive 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.
