So, the theory behind "permalinks" is that they are supposed to stay the same. I'm breaking the rules and changing mine. The good news is that because of the way Wordpress is built, links to the old addresses won't break. Originally, when I set them up, the format was: /blog/{year}/{month}/{day}/{post-title}. I'm removing the {day} because it's overkill. When looking at a web page address, it's nice to see the year and month the page was created, but there isn't a whole lot of reason to for the day to be there. The developers who built WordPress included a very nice feature that handles these changes smoothly. Bacially, if it sees requests for the old style address (which would potentially be coming in from other sites), it automatically redirects them to the new location. So, if an incoming link is pointing to something like this: WordPress will see it and automatically change it to remove the now extranious "/29" part. This is a great example of a good software design. If this wasn't handled and the format for the permalinks was changed, any links to the old format would immediately be broken. The user of the software shouldn't have to worry about stuff like that, and because WordPress developers thought about and designed for this, the user doesn't have to. It just works without really thinking about it. Another nice example of good software design is that if you remove the post-title from the address (e.g. you'll get a list of all the articles that were posted in the corresponding month. Once again, very well thought out. Kudos to the WordPress team.
