Trust is built over time - I didn't mean to point the finger at anyone in particular, but the list of failed/scam ventures from 2011 and 2012 is unfortunately long. Good luck with your site!
Thanks very much. I appreciate it. Hopefully bitcoin continues to gain legitimacy and there will be room for many of us to do very well! The best thing we can do in the meantime is operate in a fashion worthy of such widespread adoption. There will always be scammers, but I'm confident that trustworthy sites (that, as you say, have earned their trust) will be the big winners.
