For the first time I have doubts about going to Rubyconf or Railsconf in 2013. I still remember how excited everybody was on Baltimore 2011 and then, in austin 2012, I felt a lot of contentment.
Same for Javascript, all of the sudden, everything seems to have slowed down. You go to conferences and people (and speakers) are still a bit stuck on end of 2011. There is nothing really moving fast. Even shiny new things like meteor and ember seems to be moving at a very slow pace.
Also, the economic crisis is hitting the real economy hard and it influences open source projects directly.
That said, 2013 will be a tech hiatus.
