When I started this blog a few years ago, I hadn't used WordPress before, and went with the defaults pretty much everywhere. The one that bothered me, though, was the default format for permalinks: http://example.com/?p=123. That's just plain ugly. The problem, though, is somewhere along the line I messed up, and ended up with long, unwieldy permalinks like: http://blog.leafe.com/index.php/2016/08/08/on_swift/. I've been wanting to switch to something cleaner for a while, but I didn't want to break all of the existing links that I've shared. So I kept the long format.
I finally got sick enough of looking at those terrible URIs and started searching to see if anyone had run into the same issue, and, as expected, I was not along. I found the Change Permalink Helper Wordpress plugin by Frank Bueltge, installed it, and I was done! Simple! That ugly URL above is now http://blog.leafe.com/on_swift/, but the old one still works.
Thanks, Frank, for a nifty little plugin that made my blogging life easier!
