Show HN: HackerLunch - a new way meet hackers

Hello HN! Here's my November Startup Sprint project (coded in two days).

http://hackerlunch.com

It allows you to post your lunch plans and lets other hackers join you. I built this because I often see HN users are interested in meeting each other if they are in the same area.

I am not a coder, so this version is very rough. If people use it, I will work with others to build a more polished version.

I would love some feedback. What do you think? Is this something you will be using?
