Here are some links to things I like.
DISCLAIMER: as with much of the rest of the internet, these sites may possibly contain the occasional rude word/ thing/ picture that might shock those liable to be shocked. Though I've chosen these links carefully, that's not my fault. Besides, it's nothing you can't handle.
http://www.samenthoven.com. This is my homepage, the central hub of my sinister ever-evolving internet empire, BWAHAHAHAHA! erm, sorry. There you'll find direct links to all the places on the web where I maintain a lurking presence. If you've got a profile or page on any of those sites yourself feel free to add me, send me messages (I try to check all the pages once a day) or simply take a look to see what I'm up to.
http://www.librarything.com/ : A recent discovery, but rapidly becoming one of the finest things on the web – sort of a MySpace for books. Catalogue your own collection or check other peoples' for recommendations, including that of one of your (ahem!) favourite authors!
http://boingboing.net/: A terrific and constantly-updating source of news stories about weird and interesting things, some technology-based and some not. Check it out.
http://www.venganza.org/: The Church of the Flying Spaghetti Monster. Like one of the academic endorsements says, "if supernaturalism be called for, the pasta family of theologies seems the most plausible, and unquestionably the tastiest with cheese." Ramen!
http://www.worldrps.com/: Headquarters of the World 'Rock Paper Scissors' Society. Compete against your screen with their 'online trainer'. Let's see some hands!
http://www.neilgaiman.com/journal/: As if it wasn't enough for him to have written some particularly fine books and comics and other things, Neil Gaiman's blog is a treasure-trove of writerly insight and links to cool stuff. Vital.
http://www.rense.com/general72/size.htm: 'The Size of Our World'. Feeling grim? World getting you down? Click on this for a bit of cosmic perspective!
