I've just set up blog.yourls.org where hopefully I will, guess what, post about YOURLS development. I think the major stuff will be cross posted here too, at least for now, and I'll blog there about all the misc and fun stuff I never write about (like plugins! owwww plugins!)
On a WordPress related side note, the theme running on blog.yourls.org is my first attempt at making a child theme. The whole theme was done in less than 20 minutes with 30 lines of CSS and nothing more. Child themes are Viagra for unskilled and lazy theme designers \o/
