This really seems to work to hide your email address (posted on your webpage, for instance) from spambots. Thanks for the link to Philip Cartland (Flotsam) who has a snazzy new front end to his site. Go see!
Maybe you already know this: In Google, you can type in define: followed by a space, then a word or abbreviation... like DSL, RSS, DVD, etc... and it will give you an instant page of definitions. Quick and simple.
PublicRadioFan.com will give you the offerings of a scad of Public Radio stations for whatever time period you access their site, with click-throughs to their Real Audio, Windows Media or other real-time broadcasts. Pretty snazzy, huh?
