Hey Mark, it's been a while. Nicely done. You said it was just an MVP so I assume you have a product designed beyond this point. So, NOW is the time to do some validation on what those other ideas are. You have a large audience who already know who you are and are willingly giving you input.

Maybe in put down your follow ideas in short little phrases and have people provide three words on that, if they wish, along with three words on their friends. It will give you great insight into what THIS audience thinks is a good or bad next step for you.

This is a site that will not maintain interest as it is beyond a short period unless you add more to it. So the key here is to move forward quickly, even if it is in tiny incremental steps. letting the users help you make some of those choices of what steps to take can only help.
