No, seriously, don't try to get people to join Hubski in some vain attempt to get the admins attention.
A: It won't work. Reddit's traffic is huge and even if 50,000 people come here today that's a blip in their numbers.
B: It makes all of our lives more difficult and would only work to degrade Hubski into something it should never be.
If you're going to invite people, make it be people that you think would be a good fit for the community and nature of the site. Please, don't just blanket invite every person you come across. That creates more problems than it solves.
