After what's been done in the last 5 years, I have one question. What will happen in the next 5 years? The sky is the limit for the future. It's like this analogy: When you were 10 you thought you were mature, when you turned 15 you thought you were more mature and realized you weren't mature when you were 10, and so on and so on.
I can't even begin to fathom what the web will be like in 5 years.
