According to a GameDev.net news report, the IGDA has created its own special interest group on tool development.
Tool Box is the SIG’s blog, and even though there are only a few posts, there is one link to an article at Gamasutra called Swiss Army Chainsaw: A Common Sense Approach to Tool Development that was posted a couple of months ago.
Some other options for the tool building community include the forum and the mailing list.
With content creation being such a big emphasis these days, even the indie game developer could benefit from better tools.
