I don’t think I ever quite got the blogroll concept; the list of links you see in the sidebar of this page are blogs that I try and read daily.
Some of the other sites that I visit from time to time:
Slashdot competitors Webwereld (Dutch), Heise (German) and The Register. Heise is probably the best of these four, but I rarely read it. I used to read Webwereld almost every day, but a recent site overhaul made it a much worse place to be.
