Full disclosure: My boss's side-project is featured in this bundle. (That's how I knew it was going live today.) However, I just found out now that it includes all these other heavy hitting apps and services! I'm voting with my wallet as well as my HN link. ;)
I must admit, I like the idea of a themed bundle like this. Some of the other bundle deals can seem a bit ... random. It would be good to see software bundles that mirror (or support) particular workflows.
