I registered thai101.net, which redirects to rikker.blogspot.com. It's now easy to tell someone else about this site without writing down some long URL. I can hear you evangelizing now: "You've got to check out this life-changing website. Just go to thai101.net"
Maybe those won't be your exact words, but I wouldn't complain.
Links to specific pages still require using rikker.blogspot.com. Eventually this may change. I've been thinking for a while about switching to WordPress.
Update: Deep linking now works with thai101.net. It will redirect to the proper page on Blogspot.
