Whilst yesterday I didn't get any physical game dev work done, I have however just launched my new specialist website, gamedevology.com, designed to provoke thought in game developers, open minds through thought, theory and research.
I also wrote a blog post with some tips on naming games
So pleased I spotted this tool in my twitter timeline, this is perfect for tracking your #30daydev efforts!
Other achievements: Blogged about the tools I use as a game dev to manage and aid productivity, read it at http://www.liamtwose.com/tools-to-aid-game-dev-productivity/
