I love Online Conversion for all kinds of conversions.  Especially useful is the cooking section, where you can even convert between volume and weight for all kinds of common ingredients.

Reference junkies, have fun at Refdesk.  Tons of links of a useful nature there.

IMDB.com is the home of cinema buffs on the internet, even though they recently made some annoying changes.

Ravelry, for knitters.

icanhascheezburger.com -- Everyone loves lolcats, yes?
