One of the amazing things to me about Thumbtack is the new user on-boarding experience. If you're building a product that needs user signups you should check it out. Basically if you come there looking for someone to help you mount something, they take you straight there and only ask for your email address so they can send you an update when they've found someone to do the job. What they've done in the background is create an account for you, but they just never asked you to create a password. It's a small detail in the overall service offering, but I think it probably increases their user retention rate quite a bit.
