Bowie, naturally, although that has been thin on the ground the last week I see.
EJ's contests (and Strawman's)
Well thought out current affairs discussions.
The fun posts - especially those of Schitzo, Blacktropic and sometimes Shelle and FastChanges. Some of To_Dizzy's posts can also turn out really good, the religion one this week has been good reading.
Things that make me want to stay away; Threads which are just public pms between Italian alter egos. Art threads which offer no discussion just a succession of pictures with no thought behind them. If you want to start an art thread, say why a picture moves you. Threads which degenerate into unnuendo with no humour.
I would like to say they former list outweighs the latter, but I cannot, however there has been a few good threads this week, so maybe all is not lost.
