Cloud computing is an interesting topic these days.  The idea of the “internet” cloud has been around a while – but now all that mass computer power is in some ways “generally available” for stuff – social networking, web sites and more.  Good article on it here – http://online.wsj.com/article/SB123802623665542725.html its really not a new concept – but as they note in the article the lexicon of “cloud” is much easier to understand for the general public and especially the business public.  The net is truly evolving into one of the great wonders of the world.
