Ever noticed that folk using Twitter seem to fit into patterns according to what they share? Have you found that over time you begin to review your incoming twitter stream according to some sort of inbuilt filter that you devise according to this pattern? The Innovation Diaries has pondered on this and the needs that folk bring to their Tweeps. Relating this to the work of Abraham Maslow the diaries have come up with a Hierarchy of Tweets. Not only informative but quite amusing it is interesting to try to place ones self in the hierarchy and even more so your twitter friends :).
