Last.fm is seriously cool. The coolest ever. At the beta site, there are two new features which are coming out in a couple of weeks time.
taste-o-meter
The taste-o-meter shows a correlation between yourself and the particular user which you are viewing.
concert calendars
In my opinion one of the strongest features to come to last.fm is the ability to add concerts to global and user calendars. Users are able to create events, announce their attendance, submit reviews, pictures and videos too! Next, imagine a page which lists a whole set of upcoming events within x kilometers from where you live! Amazing!!!
Seriously cool. I’m imagining browsing my Amarok context browser and listening to RHCP and a little box is shown: “Hey, seb! the RHCP are playing in Sydney in April!”
I think i’m in web 2.0 heaven.
