SharePoint Information Architecture
One of the hardest questions anyone who is architecting small, medium, or large SharePoint deployments is how to set up the site collections and governance model around those areas.
Some groups say more site collections is better, some say less is better, but of course the overall saying is that it totally depends on your needs. This is great to know, but it doesn’t really provide enough information, and unless you want to read tons of blog posts and reams of Microsoft technical material (which I personally love to do) you need something thats organized well and articulates the high level concepts you need to know to make a successful implementation of SharePoint.
Well Bob Mixon has done a wonderful job of this. Take a gander at: http://www.bobmixon.com/blog/Lists/Posts/Post.aspx?ID=55
