I have two answers to this question.
First of all, I don’t know if 7,000 followers is really “a lot” of followers. Like, it is, especially considering the average user has 126, but we also live in a world where the least interesting Kardashian sister has over 7.5 million. She gains and loses more than 7,000 followers every single day, possibly with every single tweet, so I suppose it’s all relative.
The second — and more accurate — answer to your question is that I honestly try not to think about it. If I ever tried to wrap my head around thousands of people reading my dumb live-tweeted analysis of Gone With the Wind the other night (not that all my followers are big dorks like me who were sitting at home on Thanksgiving Eve dicking around on Twitter, but you get my point), I would absolutely shit.
So, yes, it is strange.
