Before check.in was release TriOut founder Lawrence Ingraham and I new at some point TriOut would need an API. What we didn’t know is how soon it would be created after the initial launch in February 2010. Then we saw the first beta release of check.in announced and I contacted my friends at Brightkite to see if they were interested in including TriOut for the second beta version and the response was yes. Some may have wondered why include a hyper-local location-based platform in a national check-in web app where the goal is to help solve check-in fatigue but the answer is simple. Why not?
