I have a similar position. If the content is valuable enough then it's tolerable to have a gate. Quibb is another similar platform, but I don't know of anything with the quality of Quora answers - Stack Overflow is the closest, but it's very specific and Quora covers a lot of content the various Stack sites don't.
