We failed to raise our seed round of funding, so essentially we ran out of money and couldn't continue working on it.
As for why we failed to raise money, we were in a crowded space and investors wanted to see some really strong breakaway growth before they'd back us, and we didn't deliver.
The site doesn't look like it's too resource intensive. Why not bootstrap it? You could get a dedicated box for a couple of hundred bucks per/month and then do some consulting to pay for it/your living expenses.
You definitely got some traction. I wouldn't give it up just yet.
Originally it was a location based "awareness" platform, with people, places, events and deals. The iOS app was the main part, and that's what I pulled. I focused the site down to just events, and now that's running on a single server. It's far from the original vision though, and no longer my main focus.
