Thanks! Yeah, I know craigslist is too big to even compete with. And I know they are offering so much for users. That's why I'm specializing. I just thought of extra features that would make it more convenient, privatized and less confusing for users.
Craigslist in my opinion is a soup of new and old products. My website/service offers a more specialized distribution of only used goods. It offers less confusion to users and gives a more detailed presentation of the product displaying their condition. I also offer two distinct features: a private messaging system, and a search-within-an-area feature (which I find is more accurate). If I am from Mountain View and want to search in both Sunnyvale and Palo Alto, I don't have to click on south bay and peninsula, I just have to key in my keyword and input "within 10 miles", and it will search the items within 10 miles of my location regardless on which area I am.
