One of the most highly requested features for http://witcoin.com
is an external commenting system like the one from disqus but using witcoins for supporting and voting on your own site.
This is a massive coding challenge however so it needs development assisstance to implement. I thought I would start a bounty/pledge drive to make it a high priority. I think not only would it help witcoin it would spread bitcoin far and wide. My bitcoins are stretched thin at the moment so i can only start the bounty with 50btc.
Anyone who's ever wished for this feature can now contribute to getting it done either through showing interest or pledging bitcoins.
