hey yesterday,
It would be real nice if you could somehow verify a new user's reviews through their ebay user account. In other words, someone could see what the seller's reviews were on ebay at the time he signed up for BitcoinHop. Their ebay username and reviews are public info but it's that communication through ebay you need to be able to do in order to confirm that it really is them. Not sure how you could legally get around that. Could some how do it to just kick start your site and when ebay frowns upon it, then you could stop doing it and hopefully by then you will be established with your users having a good number of reviews.
Just my 2 cents.
We really need a huge ebay and amazon bitcoin like sites going for the bitcoin. At least to help balance out the illegal drugs selling and stuff. That way the feds can't blame the bitcoin for being used just for drugs.
That and I really like to get out of the US dollar...
