You can buy and sell shares in me on Empire Avenue! It's a virtual stock exchange that uses people's social media activity and influence as factors in determining their stock price. It's interesting because it not only reflects your activity on sites like Facebook and YouTube but also and maybe more importantly because it acts as a catalyst for social media activity.
If you use this link http://empireavenue.com/?t=2j4ddr12 to join Empire Avenue then link one of your social media sites we both get 2,000 Eaves, the virtual currency used there. Try it out, it's sorta fun and kinda addictive.
