The good thing about 800-wx-brief is that they record the fact that you've been briefed; so if you were to have an accident, they know it wasn't due to the fact that you neglected to check the forcast.
I'm a big fan of the GA setup in the US also, but just to keep the record straight, it's worth noting that both the websites I referenced log your requests under your (free) username. That would certainly provide evidence that you've discharged your PIC responsibilities.
