New startup service Kibin, born of the most recent class from 500 Startups, is an online editing community. It works on a credits-per-word basis, where you pay credits to have your work edited and gain credits when you edit for other people. As TechCrunch notes, those who don’t want to edit for others can buy credits for 50 cents apiece. According to founder Travis Biziorek, the credits equal about a cent per word, so you pay about $10 (or earn $10 of credits) to have a 1,000 word essay edited by the community. Kibin currently has a turnaround time of about 24 hours but hopes to speed up the editing process as more users join.
