> If you want your friends to meet you at the bar, create an "Event". The event has a title of what the event is (e.g. "Going to the bar"). It has a description to get your friends excited (e.g. "$2 margaritas"). It has the address (e.g. "123 SomeBar St."). Lastly it has the time (e.g. "Tonight at 8pm"). As soon as you post it to the feed all of your friends get a notification that you just created a new event. They can then all tell you if they are going by hitting the "attend" button.
So you're making an app whose entire functionality is just one of Facebook's many features? And with Facebook already having a billion or so users -- a large fraction of which likely already use Facebook's "Events" for exactly this purpose -- how do you plan to get everyone to use this completely separate app -- that no one else they know of uses -- over Facebook?
I really do wish you the best of luck but it seems like you've got several things going against you before you've even really got started.
Just the whole "network effects" thing is gonna kill it.
