Sell t-shirts because I would totally wear one to work.
I think Digital Ocean should sell t-shirts. Cool logo, and maybe have a referral code word on the shirt so each one is customized. Like hey go to Digital Ocean and put in my name "Casey" for a discount.
We're looking into setting something up. We're not in the t-shirt business, so we don't really want to be handling this on our own. We weren't impressed with the quality of our previous online merchant. So we're looking into other options.
In the meantime, track us down at a conference and we can hook you up. ;-)
Or maybe stickers can hold you over: http://do.co/dostickers
