I'm back from PyCon UK which was probably the best conference I have ever been to. It was large enough so that there was always someone new to talk to (and new things to hear about), but not too large (unlike the med ed conference in Trondheim with ~1,800 delegates). People were friendly, it was well organised, interesting and varied, and I had a great time listening to things, having ideas and chatting away about my own stuff.
