Will SFDC be able to extend it's market share withing the Cloud?

I don't know, my knee-jerk answer to this question is DUH!?!?! (and I think it's the right answer). The SFDC that we all know and love is enjoying a 25% gain every quarter for a bunch of quarters in a row (if I were a real blogger I'd probably go look that up to have actual numbers) But this article I just read seemed to question whether or not SFDC will be able to. Seems like a no-brainer to me, but you can read it for yourself and decide for yourself as well!
