Locating expertise

Jack Vinson's "Knowledge Jolt with Jack" blog had an informative and richly-linked posting last month on the important issue of how to locate expertise on a given topic. Includes referrals to several "find an expert guides," notes on the etiquette/ethics of getting people to share their information, and the growing importance of social communties of knowledge (e.g. de.licio.us) Knowing who is in the know can be useful for everything from really tough reference questions to identifying participants for speaker programs.
