Has anyone else compared Ning to Crowdvine? I generally like Ning better, but the one feature that Crowdvine has that is very compelling is the profile answers are tagged, so it creates a tag cloud that let's you see everyone that responded to the profile question. Then you can actually see a map of where they are located so you could connect with people local to you if you want, or even if you aren't close by, you can find people with similar interests or technologies.
If Ning had that feature I wouldn't look at crowdvine. Any thoughts on how useful a feature like that is? Essential or not essential?
