There are times when the ranking of “very low” related to Spokane’s performance is actually a good thing.

So it is at Flightstats.com, a map-based display of airline flight delays across the United States. With all the travel taking place this time of year, we checked periodically to see how GEG (the airline code for Spokane International) was doing.

Generally, Spokane’s map icon showed a circle half-filled in green. That means low levels of flight delays. The same map, which relies on real-time data fed by the Federal Aviation Administration, highlights the worst delays with orange (moderate) or solid-red (excessive). Chicago seemed permanently marked by a dark red circle all last week.

Site value: moderate. It provides a quick overview of the entire nation’s air system. One can also plug in each airport’s code and get a real-time summary of inbound flights and scheduled arrivals.

If you like exploring the vast online music world, here’s another clever startup that creates a personalized Web radio station. It’s the Israel-based MeeMix, which just went into public beta mode.

This is a crowded area already, with Pandora and Last.fm both trying to make inroads with users.
