It lets hackers meet up with each other for lunch (and hopefully an interesting chat). You basically make a post stating when and where you are free to have lunch and others can join in.
Launched it a few days ago but unfortunately haven't received much interest or feedback. I will probably release another polished version in a month and see if it gets more traction.
Keep on working on it. Nice to have, can't see how it could be acquired, or make enough for ramien, or anything like that.
I am working to make the interface a bit more appealing (new design: http://i.imgur.com/KOaA8.jpg). Then I will move on to add integration with facebook and twitter and let users do more with their posts (invites, privacy, comments, geo-tagging, etc.).
As for the future, I plan to extend this beyond hackernews and beyond lunches. Eventually you should be able to post any event you plan on doing and invite anyone. Kind of like a social network focused around events.
Good to hear that you have a plan to develop it further. One problem I have with my site is to give too much features which are not required, or I dun use myself. Do guard against that too. Less is more.
