I was going to post the next installment to Building a Web Application on Friday but decided to wait until next Tuesday (it's a long weekend here in Canada). So, in the meantime, check out Squarespace. It's a hosted service with a niche market. Just like I'm looking to do. His niche is blogging. It's attractively designed and has some pretty interesting features. Definitely worth a look-see. The main developer also has a blog of his own.
So, what are you building? :)
For the answer to that question, be sure to check out the ongoing series "Building a Web Application"
