With nothing else to do last night but try to check on my social media connections, I checked out Empire Avenue. It's an interesting concept where you invest in others instead of simply "friending" them. It's much more detailed than that.
Bottom line is that it can help expand your reach to people. If you're trying to create an audience, then you want to get your name out there any way you can. I will let you know how it goes. This is still day one of my Empire Avenue adventure.
