When i first started using Acobay there weren't many users. Lately it seems like it's just exploded. I've hardly had a chance to add to My Stuff but I already have 33 people in my network and as I add more to it, I will be able to connect with more people.
What i really like about Acobay is that it's not like all the other Social Sites where you connect with people you already know. You're connected with people who have the same interests and stuff that you do. That opens doors to people you don't know yet and who knows how much that can help with marketing your blog, store, etc?
I say hurry over, join and see what it can do for you. You'll never know til you try.
