I've only attended the Future of Web Apps conference once before, and I recall having a great time there back in 2008. The quality of sessions was second to none and there are not many conferences in the UK (or anywhere else for that matter) where you can see such a great line-up of top level speakers.
The conference takes place from October 3rd to October 5th (that's next week!) in London, with Monday 3rd being taken up by workshops, and the main conference happening the following two days. Should you decide to go then please use the discount code FLASH to receive 15% off a 2 day conference pass.
I'll be attending on Tuesday the 4th, and maybe the 5th as well if I can pry myself away from the desk for that long :-)
I hope to see you at FOWA next week.
