The basic idea is fairly similar. The key difference is that, instead of you requesting someone to have lunch, the app automatically pairs you with someone.

I believe this would make the experience much more natural and fun.

Also it solves the problem, where a large number of users are only interested in having lunch with a few people (VIPs on LetsLunch).

I'm hoping this will make HackerLunch more about meeting interesting people and less about "networking".
