PEW: 28% of Net Users use Tags

Wow. There's a report out from PEW about tagging. They claim that 28% of Net users have tagged some bit of content.

That's a significant number. Tags are a key bit of lubricant in the online word-of-mouth machine. A tag is essentially an open-recommendation. If you tag a bit of content with tag X, you're telling the world "if you're interested in X, you should read this thing.

If I were you ;-), I'd start putting an "add to del.icio.us" link on just about everything I put out.
