So number limit or not? A personal limit is good. I constantly reviewed the people I followed on Twitter, trying to get the number down to the most consistently interesting users. However, a number limit might create the same awareness of quality that it did in the liking/hubing situtation.
As far as a limit, I can't personally see myself following more than a few dozen people. Maybe that will change. At the same time, sometimes the most interesting uses of a platform are the ones that aren't planned on. I'm not sure what benefit following hundreds of people might have, but I am not ready to rule out the possibility that there might be some. Of course, on the technical side, there are consequences. For the time being, I'm just going to think on it. -Thanks!
