Amateur Radio callsigns are listed if they're Hams. Due to shared technical interests, a lot of my friends who have web pages are ones whom I met through sbay.org, Stratofox, SVWUX, West Valley Amateur Radio Association, or other places/organizatios in Silicon Valley.
I'm also listed on LinkedIn, an online social and professional contact network. I don't sent invitations to people who aren't already on that network without talking to them first. The reason is due to my healthy paranoia about privacy on the Internet - I don't enter anyone else's e-mail address into an unknown web site without their permission. I request that people show the same care with my e-mail address. But it isn't possible to convince everyone to be so cautious - oh well.
Here's the list of links, alphabetized by last name...
If you're a friend or relative of mine and your web page isn't listed here, either I don't have your URL or I need a reminder to update this page. (It isn't a rapidly-changing page. So sometimes I forget to check if it needs updating.)
By the way, if you're a registered Slashdot user, you can browse my user page and use the "relation" feature to mark me as a friend (or foe), which will adjust the priorities by which we see each other's articles. See also my Slashdot Friends&Foes links: friends, fans (people who have linked to me as a friend), foes and freaks (people who have linked to me as foe.) OK, as you can see, the foes feature of Slashdot isn't heavily used. :-)
