Something that I'm trying to get to on Sunday is NotCon - "an informal, low-cost, one-day conference on things that technologies were perhaps not intended to do". Given that it's effectively a terse ETech with a Brit twist it should be seriously good and funny, and as conferences go at 4 quid (3 for bloggers and concessions) it's a steal.
The quid saved should go part way to buying a Joi Ito a beer at the meet up afterwards, although it wouldn't do much to pay his phone bill...
Nice to see it's getting some good coverage from NTK, El Reg, The Industry Standard, The Guardian, and Boing Boing.
If you can't make it to NotCon, there's a #notcon channel on freenode.net with public logs at http://www.cs.kent.ac.uk/people/rpg/pjm2/notcon/ which ought to provide ascerbic commentary on all the action.
