I won't be attending for many reasons including - but not restricted to - no money, not knowing London, not knowing any DiSers, not really knowings what it is, nowhere to stay, fear of feeling out of place, having other things to do on Saturday.
So, who's not going? Why are you not going? And do you think you'll be missing out?
Personally, I think it sounds pretty amazing but such is life. Maybe next year...
