This is an odd coincidence, one of the Dead Man's Switch subscribers asked me if I supported Bitcoin, and I ended up adding a MtGox button on the site (it's pretty nifty, it even autoconverts to whatever currency you want and supports IPN):

I've been warming up to Bitcoin, the same subscriber clued me into https://blockchain.info/ and it looks pretty good. The only thing I'm worried about is that Bitcoin isn't very stable, but I don't really care since MtGox autoconverts all payments. There's no downside in accepting it, as far as I can see.

Plus, I can just keep them as Bitcoins and pay right away with very low fees.

EDIT: I also decided to dabble in a bit of MtGox trading with my newly-acquired 4 BTC, so I sold high and bought higher. It... didn't go very well.
