BananaBucks are just a fun thing we recently introduced to encourage participation and be rewarded for it. They are like monopoly-money really, but can be used to enhance the look and feel of your posts and your profile, check out the BananaBucks Shop for the current list:

We will be making banana plants available soon as well for those who want to trade their earned BB$ for real live banana plants!
BananaBucks caused some confusion, concern, and controversy when we first introduced them but I think it will grow to be a fun thing. The rather large thread about BananaBucks is here:

There aren't a lot of people selling tissue cultured bananas here at this time but feel free to get your kits out there, teach us how, and help change that!
