a couple of more users signing up and you will see the magic happen. The positions of teams will keep switching, points increase and markers appear in real time.
This is similar to the Represent.la project for startups, except for Football fans. You can deduce a lot of interesting things. Which team is popular in which city and country, who is the nearest fan to you, spotting friends nearby, favorite hangouts for each team's supporters. Can also be extended to fan club meetups, cheers during the match etc.
Agree, asking for a sign up is a strenuous process.But this looked interesting to me and i signed up . They have my location and team preference, Enough data for them to start with I guess.
