I'm using Blender 2.6 to create meshes to be loaded by my engine while in development. I've noticed that Blender 2.6 has very few exporters compared to previous versions of Blender (but a MUCH improved UI). I was using the FBX exporter since there is the FBX SDK to keep the model loading code from being too large (as opposed to a Collada parser). It seems that FBX wasn't such a good choice since I've started to notice that the exporter is terrible (It doesn't export light DecayType, material colors/intensity and many other things, it leaves them at zero).
What exporter in Blender DOES work well? I'd prefer one that exports to XML since it can be opened in a text editor to fix the paths.
