Trollim: the battle of programmers 1 on 1

At the recently held TechCrunch50 conference, a rather interesting Trollim web service was presented . With it, programmers in one-on-one battles can figure out - which of them is cooler? Programmers are friendly here called "trolls", hence the name of the site.

Register, specify your skills (C ++, Ruby, PHP, etc. on a scale from 1 to 5), then pass the basic test for confirming skills - and you are ready for battle. The battle lies in the competition, who will quickly find and correct errors in the code in the most effective way. It seems to be quite an exciting lesson ( video ). They say that it looks like a cross between Facebook, World of Warcraft and Sourceforge.

The usual battle is held in 1: 1 format, although there are other formats. The rival can be selected by place of residence, gender, age and other parameters.

The startup plans to generate income by attracting companies that can sponsor battles, offer their tasks and prizes, and also find talented programmers here.

The service can be used to screen candidates for a vacancy. Let's say there are 128 candidates. Let them determine the best on the Olympic system for knockout, and already the winner, tempered in battles, can be invited to work.
