Ra-Ajax just released Stacked, an open source version of the excellent StackOverflow.com. It is a great way to handle questions/answers, product recommendations etc. so an open source clone of StackOverflow is a great idea as StackOverflow is focused on programming. Now you can download Stacked and create a StackOverflow type site covering whatever topic you want. Great. While the design is far from perfect I expect the code produced by Thomas to be as close to perfection as possible. Thomas is fanitical with open source so naturally it supports OpenId
Ra-Ajax is a new company by Thomas Hansen, the founder of GaiaWare. I covered them earlier and was astonished to se the new turns this company and Thomas has taken (will explain later).
