The weblog which you are now graciously reading has just been upgraded to feature threaded comments (so step out of your RSS reader and try it out). Incidentally, I’ve been yearning for threaded comments for years, so it’s nice to be able to strike that one off the list.
As part of the upgrade, I’ve had to sacrifice the ability to quote comments; an ability which you probably didn’t know of and won’t miss, especially now that you can reply directly to a comment. Good riddance. Unfortunately, the ability for commenters to edit their own comments was also sacrificed; do you know of a 2.7 compatible plugin that does that?
Finally, hello Gravatars! Since—2004 apparently, oh my how time flies—comments have featured favatars, mini-graphics built from the favicons on commentators websites. Gravatars are bigger and therefore more fun. Plus, if you don’t have a Gravatar, your comment will feature an amazing identicon, a tiny graphic symbol built from your IP address (don’t worry, it’s an irreversible process); which is awesome, because as we all know, pseudo-random artwork is great. In fact, I like identicons so much that I think you should get rid of your Gravatar and then post a comment here. Do it for me.
