Ah yes, the old Putnam thread which gets trotted out every month or so...
I know where my limits end, and when my product is ready to go to the next level, I'll have no problem bringing on a VETTED and qualified partner to grow the company as fast as possible.
Sure. One of the bullet points from my talk which didn't get translated into the blog post was "Step 1: Figure out what you're good at". I'm very much aware of my limitations, and if I ever forget them tptacek will step in to remind me how horrible I am at web design and how I need to do a better job of selling Tarsnap.
As for marketing, I very nearly listed Hacker News as my marketing co-founder: Roughly 10% of Tarsnap users come to the website from http://news.ycombinator.com/item?id=389304 -- far more than any other single page (although my blog is more in aggregate).
