I have had a love-hate relationship with Twitter. I am more active over the weekends when I scan my feed a few times. During the week I seldom scan my feed. I always find my timeline to be noisy even though I unfollow often. If I am catching up on tech news I prefer to just scan tech news (either in Flipboard or Reeder) rather than scan my Twitter timeline which also has a lot of other stuff thrown in - random conversations, retweeets etc. I have tried Twitter lists but it just doesn't seem to stick.
