Yahoo! flickr & upcoming Web 2.0 (3.0) social media mashup !
Yahoo! have actually built a web 2.0 (3.0) mashup into their Upcoming site !
I just clicked on the "My Scrapbook" link and got a mashup of my last months (upcoming) events together with all the associated photos (presumably it uses yahoo flick upcoming machine tags and api) !
Very impressive (but slightly scary) esp when you factor in Yahoo Smart Ads !
