We've made some changes to how the urls look to make them 'pretty' and make them (hopefully) more intuitive. So, for instance, to get to your user page you go to something like hubski.com/user/forwardslash instead of hubski.com/user?id=forwardslash.
The process of making this switch was finicky to say the least, so it's more than likely that some url won't have changed over or will break. If somethings not working right and it was last week, probably has to do with the url rewriting, so ping us and let us know.
Also, all the old urls should still work, so we shouldn't have dead links floating out there like trash in the ocean.
