I wanted to play around with Bootstrap 3 yesterday so I made a site for my Minecraft server, check it out: http://treestop.com
The first page are global stats, but they are based only on people that have statuses at least 60% in Latvian tongue. That means it analyzes your statuses, your followers/following person statuses and goes further. The profile page will have more personalised information for you (unfollowers, influencers etc.), but I have to work on that bit more.
Nice, man. I played around too, developing www.twi.lv (twitter stats for my region), but mostly it was not for Bootstrap, but advancing skills in SQL. :)
