Thanks for update! The best use for the flirt coin is to be a way to unlock features on the website, or to improve the ranking of the user. Many social networking sites have such pseudo-currency.
There is one thing I don't really like among the latest changes - the website requests registration now as soon as you open it, so you can see absolutely nothing unless you register... But if I don't see anything, what will make me register? As to me, if I open a website and see just a box to login or register and nothing else shown, I will just close the window. There should be at least something visible, which could be interesting enough for user to bother registering!
