With the large code change in WordPress 2.3*, it seems some bloggers are reluctent to stay with WP 2.3* and have reverted back to using an older version of WordPress. This is due to bugs and compatibility problems mainly.

Personally, I find WP 2.2.3 the best bet for the time being. It is stable and has the latest security fixes.

I’ve learned from rough experiences never to rush to upgrade to a new major release, cause there are almost always kinks to sort out. I’m going to wait out as long as I can.

As a side note, I hope bloggers who are reverting are using their previous backups to do so. Simply replacing older WP files over your newer WP files could cause all sorts of problems.
