There are a couple of good bitcoin business directories. Bitcoin businesses related to clothing, real estate, marketing etc are listed in these directories. I think these directories are only helpful to those who are running either a large or small bitcoin oriented business. My idea of a bitcoin directory is entirely different, it is targeted at people who are new to the world of bitcoins. The only way this could be done is by compiling a list of all the best bitcoin earning sites, there are 1000's of sites, but categorizing them will definitely solve this issue. For example, there is a micro earning section in BT which is awesome. A newbie could easily find newly launched bitcoin faucets in this section, but still there is not a subcategory for everything. For the time being I have categorized bitcoins sites into:
Bitcoin Micro Earnings (PTC, faucets, rotators)
Bitcoin Blogs (personal as well as professional)
Bitcoin P2P Lending
Bitcoin Ad Netowrks
Bitcoin Cloud Mining (only legit, this category might remain empty forever
)
Bitcoin Exchanges
Bitcoin Forums
Bitcoin Wallets
Bitcoin Games (non-gambling and gambling)
Bitcoin HYIP
Bitcoin Trading
If a website has an official bitcointalk thread then it should also be posted with the listing, this would help in identifying scam and taking down the listing.
I already added a couple of sites (no referral links),
