Definately a good talk, and really inspires me to try and finally get something built and released in my spare 10 hours a week.  I have been messing around with various projects over the last year or two, but it takes a long time to get anything decent done in 10 hours a week with one person before the motivation runs out.<p>One thing that just occurred to me, is that while DHH was working 10 hours per week on Basecamp, I'd bet that Jason Freid was putting in at least 10 hours on the design side too.  For me, the programming side of things isn't the big time sink - its getting the application to look and flow correctly.  I would guess that for every 10 hours I spend coding, I spend at least that trying to get the UI to look even half professional.<p>Thats not to take anything away from the achievement of building Basecamp in spare time, more an observation of how much more productive I would be if I had someone doing the UI elements along side me.
