This upvote exchange now has 1180 members and has been growing fast within the past week. I'd say it's added 1000 members within the week and it will continue to grow. I've seen a bit of activity increase as well. My pending upvote was at 1.60, but now it's at 1.47, which happened overnight.
So that means 0.13 worth of upvotes have been applied to my most recent post. This site is doing good and I believe it's going to be big within a month. If you're a minnow join fast because this will help you get off to a great start. Feel free to check it out.
