I saw it on the news this morning, didn't feel a thing though (I'm just outside Sacramento, so too far away I guess...). Sucks that some of us MW'ers had our collections thrown around, but it seems liek the quake was fairly harmless and no real damage was done... and that's a good thing.
Makes me think about how people from the east coast and midwest always tell me about how dangerous they think California is because of earthquakes, but that's a real exaggeration. I've lived here for almost 20 years and only felt one or two earthquakes (small ones). I guess it helps that I don't live in the Bay Area (though I lived in Northridge for a year and a half) but seriously, California's earthquakes are overrated.
Er... Except the big ones, but those are pretty damn uncommon.
