I remember signing up with these guys when they first launched. To be honest I haven't used them since (due to lack of flights to certain places), but they've certainly evolved a lot since then. Congratulations are in order!
Same here. I remember thinking it was a cool idea, but they only tracked certain kinds of flights, so the service was useless for me. I checked again a few months later, and there didn't seem to be any progress. I never checked again. Suddenly, Microsoft values them at $115 million.
Me three...
Are there some simple percents on beta tester burn rates when the product is unfinished, but appears promising enough to sign up and try it. Best guesses?
