Awesomeness of last.fm
Last.Fm is a really awesome (to use this vague term) web 2.0 site. This site is in an ideal position in the market. What started as a simple this-is-what-I-listen-to stat site grew to a much larger community site, where people can find and share information about music. People still share their statistics, and this information is used to your own advantage. Music recommendations for example based on what other people listen.
My latest really great experience is this: A Paul Gilbert concert. Last.fm gives you a load of event recommendations based on what you listen. If it wasn’t for Last.fm i would have missed this concert. Now I wonder, do they cooperate with the ticketmaster service? It would make a lot of sense if they did, this is clearly a win-win situation for the site (commission) and for the ticket seller (more costumers) and the user (more concerts!).
