intpforum.com (of course)
thedailywtf.com (job-related curiosity)
nu.nl (dutch newssite)
tweakers.net (dutch tech-site)
buienradar.nl (site that shows where and when it's going to rain... sad, but it exists and it's functional too)
and when I'm really bored I might see if there's something at bash.org which I still find amusing...
Hm, that be a hard thing to do for me, to pinpoint some 'Most wanted'-Websites of me. As opposed to some previous posters, i spend, if i have the time (i often do) at least ten hours and more on the internet. So you can guess that i visit many pages.
Of course there are some more frequented than others. This forum, wikipedia and others. Some sites i have 'migrated' into my feed reader. I have some 20 newsfeeds or so.
I know, there are many people using the internet a lot more intense than me, but i am above average too
Start with Gmail, Facebook and intpforum
If I have time I move on to OFClan.net (I'm an admin so they expect to me to have a presence) and Spikedhumor
I randomly access several times a day Wikipedia, Youtube, CNN and Amazon
hotmail.com - for email
intpforum.com - for learning
google.com - for research
youtube.com - just for kicks
dictionary.com - for big words,lol
pokemonglitches101.com , I admit it... old fan (I'm a moderator)
I used to check:
deviantart.com - for my charcoal art
xanga.com - as an online journal
intjforum.com - for a bit of morbid humor (i.e. "The NF Club", lol)
Youtube most days for fun
Politico for not so much fun
Here of course
All Hat No Cattle for a laugh or two http://www.orionsarm.com/ cuz I'm geek enough to like it but not geek enough to contribute.
Too many political blogs to mention....
And when someone irritates me I link this to them: http://www.albinoblacksheep.com/flash/youare (turn down your volume if you are at work....or not)
