Here is a great new website that needs just a little bit of help to get it going.
WikiAir.com will one day be a very cool site to visit whenever you expect to be in an airport. The idea is that anyone who has tips on the best things an airport has to offer, such as free WiFi or best places to sleep, will write up their recommendations and post it on the site.
Unfortunately, the site is still too new to have enough relevant data quite yet. For example, I visited the LAX link, a place I tend to spend a lot of time, and there was nothing other than a listing of which airlines flew into which terminals. It was a little disappointing. I plan, however, to check back in a few months to see what cool insider tips travelers have posted.
