LANGUAGES:

Artificial Language Lab. Hours of useless fun playing around with languages that should never exist.

World Wide Words. Vocabulary site with sections for truly obscure words, recent additions to the language culled from today's headlines, and, of course, useage notes.
The ChomskyBot. See if you can make sense out of it...

Congressional Quarterly. Great resources for the "concerned" voter: rate your congressperson(s) (see how your votes stack up against theirs!).

WEB SEARCH/INDICES:

The CyberTimes Navigator. The home page used by the newsroom of The New York Times for forays into the Web (great links to search engines, etc.)

STUFF:

Bowtie tying. I'm a huge fan of the bowtie. Unfortunately, I so rarely have the opportunity to wear one that I still need coaching...

megaConverter. "The web's best place to figure what equals what."
Phonespell. If it weren't for this site, no one would call me.
Cliché Finder. Have you been searching for just the right cliché to use?
