I hate to waste my time on facebook because almost all my activities are lost for me. In general, there are two important feedback cycles: one is social - the other is between me and myself. If a platform makes it impossible for me to build an external knowledge base (or gossip, or fun, or photos, you name it) that is of use for me then I question myself why to put any energy into it. Hello fb, where is the stream or even better rss feed of my likes and other contributions that I could reuse and review and enhance as I like and whereever I like?
