Since I know f2p and freemium are big topics on these boards, there is a neat conference next month (well in about 20 days) in London. http://www.f2p-summit.com/ is the web page for the event. I went to it in September and had a good time. I still hate cash shops, but there is lots of good folks and tonnes of information to be had about f2p from the developers point of view. It is definitely not free to attend so might not be for everyone.
