Well, 10th anniversary art contest was something crazy. Many members showed how creative they are and created amazing artworks. On the other hand, there was so much shit and abuse. Nothing surprising, people were attracted by easy opportunity to get merit. And I'm actually not sure that theymos was happy that he made so much work for himself. I think it wasn't easy to get through all works and award so many merit
11th Bitcointalk birthday probably should be celebrated too somehow, but obviously not as big as 10th. IMO, repeating such contest again would be boring, we need something new. Maybe it's too early, but we can start to think how 15th or 20th anniversary should be celebrated .
