I tried the application. Here's some of my thoughts:
1. You can't explore before registering.
2. The only tags are software development related.
3. The exploration/filtering by age or country is none of what I'd want to filter by. I'd only want to filter by "interest" (things beside programming, which isn't there).
With that said, good website otherwise - didn't hit any other problems and fairly straight-forward.
1. Level of prior exposure to overall subject. Someone who wants a refresher or go a bit deeper into a specific topic may not want to be in a study group with someone struggling to setup an editor.
2. Time commitment. Someone looking to spend an hour or two a week probably won't mix well with someone really committed to taking courses.
