It took me 2 weeks from hearing about bitcoin to owning it.
2 months for me... one to research it thoroughly to find out it wasn't a scam, and another to figure out how to actually obtain some, watching helplessly as the price went from $15 to over $60.
Yeah, 2 months is about average to thoroughly research Bitcoin. In fact, I'm still learning tidbits here and there.
I remember calling Gavin and theymos at least a couple of times to ask questions. Then wasting another month throwing out low ball bids on OTC that were laughable (embarrassingly low). Finally I said fuck it and plowed into mtgox.
