ThatHigh.com - my pet project

http://www.thathigh.com

I started this as a funny project with a friend and it ended up hitting the frontpage of college humor and we got a ton of traffic.

i'm wondering if anyone on HN has any advice on how to pursue this as a viable business. i talked to a lawyer from NORML and it seems to be in the all-clear freespeech-wise, so what should i do next?

I plan on getting some bumper stickers to post around my college campus and possibly order some tshirts to sell. in about a week we've made around $50 from adsense. any ideas HN?

EDIT: some stats - we have over 1000 submitted stories and almost 300 registered users already, and our hits have definitely dropped from last tuesday when we were soaking up the traffic from college humor.
