I wanted to follow up on my last post (What the BIM are we Talking About?!?) with a couple of recommendations on BIM orientated blogs that I keep up-to-date with myself.
There are many out there, and I certainly haven't seen them all, but two that keep me coming back are 'Practical BIM' by Anthony McPhee & 'BIM Fix' by Brian Renehan.
Both blogs have posted recently about what is behind Level of Development (LOD) too if your looking to explore this & many other aspects to BIM in more depth.
For an extensive list of many more BIM blogs out there, I would recommend visiting Revit OpEd. Steve has put together a fairly healthy list of what is currently out there.
