I updated my WordPress permalinks from an old-fashioned and quite outdated /%year%/%monthnum%/%day%/%postname%/ to the more optimized structure /%post_id%-%postname%/. Although I still like it if I can see the date and the entry title at a glance, the new structure has two advantages:
- the new permalink structure is in some cases faster because of the way wordpress stores the URL information in the database (see further: Efficient permalink strategies for WordPress)
- according to SEO’s, a link like cordobo.com/540-firefox-add-ons-for-developers/ is more likely to result in a better SERP position than (the same) link named cordobo.com/2008/09/30/firefox-add-ons-for-developers/
