I'm a on/off twitter user -I go through bursts of using it, and then I ignore it for months. When there's a news event I'm interested in, I tend to search twitter for keywords, or the relevant #hashtag - as a news consumption service, using it in this manner works quite well. However as others have said, unless you are in the 1% that have millions of followers, you are basically tweeting into a vacuum; it's effectively an anti-social network. My main problem is how to organise it all. I don't have time to endlessly scroll through a mixed bag of tweets in one stream - I tried tweetdeck, but my preferred usage model would have resulted in 100s of columns, which isn't right either. Am I missing a feature here? i.e. is there a way to create filtered 'lists' that I haven't found, or do I need a specialist client?
