If I recall correctly, the way the URLs currently are is due to the way the backend is hacked/set up. I definitely want to have pretty URLS, better multi-urls/filtering URLs, etc. at some point. I especially want to add post titles to the post URLs so they are a little more interesting to look at instead of just a string of numbers. I think it's a matter of effort vs reward at this point; the amount of work it takes to set it up is far greater than the reward. I do like the idea of having a way to see two tags at once - or two users at once - or whatever. reddirecpthoo, you would probably be interested in this: https://hubski.com/pub?id=143618 Also, you can create lists with posts and comments: https://hubski.com/pub?id=121928 I believe that's all the URL hacking available right now.
