Check out a blog called Trendsspotting. It’s written by Taly Weiss, a social psychologist who runs a market research firm in Israel. She’s recently wrote about a bunch of interesting topics including:
Self testing the degree of hardcore Web 2.0 usage.
Crocs. (There are two pairs of Crocs in the Kawasaki family!)
Influence of MySpace and YouTube on shopping.
The posting that you’ll enjoy the most “proves” that bloggers are egotists. :-) Between Trendsspotting and TrendHunter, you’d have trends covered. (Trendsspotting focuses on psychological studies; Trendhunter focuses on products and services.)
Note that the word “I” isn’t used in this posting! :-)
