OK I guess I am nutty enough to be perfectly equipped to give the nutshell overview of Empire Avenue.
The quick overview of EA is that it is a site that is based on evaluating & supporting your social media activity. The currency is eaves. You get eaves by doing missions (SM activity) for others. You get eaves when folks buy your stock. You can purchase eaves also, but most eaves are generated by investing…that is purchasing the stock of folks with strong social media networks. Although my shares are expensive (1436.72 per share), I generate about 2 eaves for every share that you own. A Newbies shares are cheap (less than l00 per share) largely because the social media activity only generates 0.10 or 0.20 eave per share.
You can use eaves to purchase stocks that may generate more eaves for you. I got around 27 Million eaves yesterday. You can also use eaves to fund missions where you get folks to support your social media causes.
Hope this helps you understand a bit. Read the help files, the Wiki site, watch the videos, or join some of the communities for additional help.
