A list of trusted Bitcoin websites? Is there some trusted website that maintains a list of Bitcoin-related websites and their reputation? For example, if I wanted to check if betsofbitco.in is a legitimate websites (it pays rewards fairly, etc.), where should I turn, asides digging through the forum?
there is no list of bitcoin trusted websites, but you can check some things  to have a good idea of the trust you can give to a website : 


check the whois :


anonymous whois ( domainsbyproxy or other ) : -1 
recent website ( created 1 or 2 months ago ) : -1 
old and known website : +1

check the bitcoinpolice website ( bitcoin.crimeunit.net/wiki/index.php ) there could be a report here ( bitcoin.crimeunit.net/wiki/index.php/MyBitcoin as an example )
if you can use IRC, come ask on #bitcoin-otc and #bitcoin-police IRC channels on freenode IRC server
bitcoin-otc is a p2p bitcoin exchange, building a reputation system ( wiki.bitcoin-otc.com/wiki/OTC_Rating_System ) , if a website is operated by an old and trusted otc member ( example of old trusted user :  bitcoin-otc.com/viewratingdetail.php?nick=ne0futur ) you can probably trust the website.
help us making it better, report any problem to the bitcoin-police
