Tinderbox was something I paid for (and wanted to love) but it was just too bloated and buggy. The creator's stance on "artisan software" is intriguing, but frankly the software doesn't put him in a good light. I'm willing to pay good money for good software, but $180 for software that feels like it's an open source alpha project is annoying, especially software that is meant to contain massive amounts of connected data.

Thanks for the links! I'll check the rest out.
