GasBuddy.com - lists gas prices in the neighborhood gas stations, updated daily by volunteers. In the Boston area today the prices range from $2.03 to $2.36.
SideStep.com - metasearch for travel sites (includes both consolidators like Orbitz and Hotels.com and individual airlines and hotels, like AirTran; of course, SouthWest refuses to participate).
A9 - Amazon's new metasearch engine. Haven't really used it that much yet, but looks cool, so I will start using it more.
DevX.com - the answer to my question from a few months ago about a reputable development portal
Я подумала, насколько же я мало сейчас сайтов использую, все сконсолидировалось: livejournal, gmail, google, maps.google, yahoo, audible, amazon, dell, orbitz, [airline sites], britanica, imdb, andrewtobias, [wharton sites], economist, yandex, priceline, [personal credit card and bank sites], netflix, weather, [work-related], ebay, overstock, [financial sites like bloomberg and smartmoney], [a few more personal sites]. That's all, folks??? I guess, the answer is that I get the rest through searching on google...
