I am normally the last person on the Hubski team to suggest or endorse anything that makes it harder for someone to join the Hubski community, however if we were to do it, I almost think that now is the best time. We've done a great job cultivating a community of smart and capable people, this would be one way to ensure that it continues down that path. Plus, if someone cared enough about joining the community, they could sign up on an open enrollment day. I like the idea of the first of every month being "open." I'm still digesting the idea, but I think there is merit to it. Who knows, you might actually see the site grow at a faster clip than it is. Nothing is more appealing than the club you can't get in to, right? Plus, when ya'll are equipped with official "invites" you may use them more often.... What do you think?
I would think the point of limiting the enrollment would be to get rid of those that aren't serious about joining. If it's just once a month or you have to petition someone you know to join, you are more likely to stick around, kick the tires etc. Those with short attention spans won't come back on the first of every month, but those sincerely interested in Hubski, after lurking for a month or so, are likely to come back and sign up. I don't think it's too frequent. But I could be wrong.
