First off – Great question! If I could go back to last summer when I started blogging I would have redone my url structure. Right now its / %year%/%monthnum%/%day%/%postname%/ but I would have liked to just have done /%postname%/ I could always change it now but the redirecting urls and all that is such a pain in the butt. There are really so many things that come to mine that I would like to do different but then maybe my blog would not be what it is if it was different? Maybe my bad grammar and bad web design makes it what it is ?
