While this is always going to be my main website, I do have a couple other websites where I keep other stuff. A couple of them I run myself, and I keep them on separate sites because it allows me to simplify the server maintenance and to allow for safer experimentation. For instance, this site runs Drupal and the photography site runs Coppermine Photo Gallery.
So here are the other sites I either maintain or use:
My photography website - photos.cosky.com
I like photography. Not much more to say about it, except check out the photos sometime if you get a chance.
My music website, rezzer.com, named after my pre-EverQuest game name which I still use in online music circles but unfortunately with the advent of "rezzing" as a game mechanic the name has lost it's original meaning which is related to the movie Tron. If you're a geek you may get that reference.
LinkedIn is pretty cool because it keeps me in touch with friends who have also managed to survive the trials and tribulations of the gaming industry.
This is a great service and has helped me to organize well over a thousand bookmarks into something that I can actually use and share across different PCs. Very handy. I try to share interesting links here.
