MVF, a hack created by Alex Taub and Michael Schonfeld, blew up last week, giving thousands of Twitter users the opportunity to indulge in who their most popular follower was. The Web app went viral and got tons of press, signaling just how important this sort of information can be to users, and perhaps signals that sites like Klout aren’t providing the right kind of data.

MVF for Twitter is so simple that there’s really no reason not to give it a try, which is likely the secret to its success. Now, the creators are back with a second tool, MVF for Facebook which controversially allows anyone to find out their most valuable Facebook friend based on a weighted combination of the total number of friends and subscribers.

From the creators:

Value is hard to define. We build this application to try and do that. We look at value as one would look at a commodity. The more scarce it is, the more valuable it is. This is what we had in mind when determining value. We also took into account popularity, for better or worse.

We tried to find a good balance of popularity and scarcity. It works at times, other times it doesn’t. We think it works more than it doesn’t. But you, the people, will be the judge. Feel free to email us by using the feedback button on the left. Please email us with suggestions, comments, or just curse us out because this stupid app was made by morons

To use the tool, all you have to do is sign in via Facebook and you’ll automatically get your MVF. You can find out your top 5 MVFs if you decide to share your #1.

At the moment, this is just a fun hack, but there’s serious potential for this kind of analytic data to provide a lot of value for companies and individuals. Also, it’s just plain cool…so check it out!
