I read somewhere lately that you should change your permalink structure to read as the title of your posts rather than just a number (i.e. http://alexmclean.net/?p=1282 should read /I-Heart-Loops instead). The point being that search engines can make much more sense out of the title than just a number.
The struggle I am having is that I imagine once you make that change, you break all your old links, right? Now I’ve only been blogging for a little over a year, but I know that I myself link to my own posts all the time, and every now and again people link to my posts from their blogs. So do I make the jump now and just deal with broken links or just stick with what I’m doing now?
