words of the day:

interstitial - relating to or situated in the interstices
It seems that interstitial may be turning into another word for a flash-based "commercial" on the web....but no one wants to say the dreaded "c" word. so we have this monster. Try a search on google for interstitial, and you'll see what I mean. The promise of high bandwidth brings the promise of your favorite website interrupted every 15 minutes by a heavily branded flash animation. *shudder*
