Joshua Schacter was one of the spokespeople (along with Bradley Horowitz, danah boyd and Stewart Butterfield) that we used at Yahoo! to show how the business was changing from a stodgy online media company to a consumer generated content nirvana.
He is a plain-spoken down-to-earth kind of guy, who is real easy to work with as a PR person. I am sure my ex-colleague Kathryn Kelly would have liked this quote from a profile piece in MIT's Technology Review:
If I went in there and said, Hey, you're using that tag wrong, people would just tell me to fuck off
The profile is well worth reading for the even-handed discussion it provides on folksonomies (tagging as its known to common folk). Kudos to Valleywag for the tip.
