sharepoint as a CMS? any experience

The composition of your message makes it pretty clear that you are looking for reasons against sharepoint but want some justification before saying what you already know. Microsoft doesn't own the internet, I'd say that the majority of blogs out there are predisposed against Microsoft because its popular. Go on Google before asking on forums, the first few results for "sharepoint as a cms" talk about some of its issues and certainly aren't "Microsoft's biased sites"
