Web 2.0 continued

The number of web pages is in the billions and I expect it won't be long before the sum total of all mankind's knowledge will be available if it is not already... and then some. I have been enjoying my journey thru Web 2.0 with Learn 2.0 and 2.1. I have learned about many things that I didn't even know existed as well as some very useful sites. I hope this will continue.
