Ha! I didn't realize about '/'. I asked in #startups about giving my old thread a bump but no one responded. So I tried making a new post and it worked!
I didn't know about the / approach but have used the "?" suffix "trick" a couple of times over the years when submitting things that other people put boring/inappropriate titles on that didn't catch on. I believe # will also work since AJAXified URLs need to be supported.
