And thank you for your comments when we met -- talking to you was the highlight of the weekend for me (I didn't mention it in the blog post simply because I don't like "outing" people, in case they didn't want their presence at an event to be widely known), both because "Hey, it's tlb!" and because of the confidence you showed in Tarsnap's potential. Thirty seconds of talking to you was more inspiring than the rest of the weekend.
As for finding a co-founder... you're not the first person to say that, but after 8 years of writing code I really don't think I could bring in a co-founder at this point.
