Bravo to the OSS Watch guys for tackling this hoary issue straight on – the best way to fight ‘fear uncertainty and doubt’ is by talking about the issues and showing how one can address them. Not that I know of any open source project that have this problem, ahem, but this short piece contains the sensible advice to make mailing lists, chat logs, etc., accessible to search engines and bookmarking systems, as well as to encourage new users to contribute documentation as their first contribution to the project. – SWL
