Just saw a talk from Ben Hammersley at reboot8. Best talk of the day and not even the keynote! Lots of things about social software and even blogging. Meeting new people as well. All pretty good. Quite a lot of Opera people here as well.
I totally agree with you. Ben's talk was the best. I have never seen anything like it.
Have you ever seen anyone giving into peer pressure and extending their talk unprepared? Amazing.
