What's so strange is that I don't even recognise this description of twitter, and I've been using it for many years. My feed is almost entirely tweets from people I follow, with the occasional ad. I don't even understand what you mean by "network" as distinct from the people you follow. Can I ask, if you can recall, how many people you followed? It's possible that there's a minimum threshold to avoid noise.
