I did the same thing with trying to avoiding politics and entertainment, and just following programmers and development thought leaders. Yeah... They almost all wind up being political too. I simply cannot find a way to find interesting accounts that don't wind up talking about politics and current events. I don't care. I don't want to use Twitter for that, but apparently, Twitter doesn't want me to use the service for anything ELSE. (And, before someone suggests it, yes, my list of muted words is already long.)
A few years ago I remember trying out twitter and following John Gruber. Back then I was interested in what he had to say about Apple, but instead I got a mix of Apple stuff and, IIRC, inane baseball updates. I remember thinking that it felt like a real step back to have such a mixed feed, compared to just subscribing to his daringfireball.net RSS feed.
