witcoin (http://witcoin.com/) is a social news site (think reddit) powered by bitcoin. To post, reply and upvote costs a fraction of a witcoin (1 witcoin = 1 bitcoin); this is distributed among the original poster/replier, previous upvoters, category renter and site dev team/charities chosen by witizens [1].
Depending on the category you post in your mileage may vary. http://random.witcoin.com/ has a post cost of .00000001 for instance.
To promote witcoin.com I am giving away 0.05 witcoin (0.05 BTC) to the forum users that sign up on http://witcoin.com/getwitit and post their witcoin.com account url (for example http://witcoin.com/witizens/7) as a reply in this thread.
Please use this gift to post content, send replies and upvote on the site; but you are welcome to withdraw witcoins for bitcoins.
For more information about witcoin, read their FAQ at http://faq.witcoin.com/ and if you have bug reports and/or feature requests use http://meta.witcoin.com/ (bug reporters are currently rewarded).
