Jeffro,
Thanks for posting the link to this resource. Excellent writeup by Ryan and certainly some good ideas to chew on when it comes to e-commerce and developing niches within your existing website.

Oh, and because of past experience I was a bit surprised on the wp-ecommerce choice. That's going to make me take a second/third look.

Do you have any plans to put these tips to work on the WP Tavern?

Good times!
