What does Obama mean to my world ?

Today I watched Barack Obama's inauguration on bbc news 24 online while I was working at home. It was neat, diplomatic and I was impressed with every word of the president. He is not Doraemon so we can't expect him to sort everything out instantly. I reckon he needs two terms to demonstrate what he can do, like Tony Blair did (for the better or the worse).

I don't understand the people who want to be in charge of a country, it's a big job, you know? Here comes Obama saying 'let's move our lazy ass and do something to sort out our country'. It must be a good kick arse for Americans. Good luck everybody - woohoo

Last fm

Today I am very happy with Last fm for the first time. I managed to find TecRoc by Discoray and listened full song. However, I still don't understand - what is scrobbler? - do I have to synchronize it with my iTune? - do I have to pay? Since signed up in January 2005, I still don't know how to enjoy Last fm fully.
It is amazing we can find and listen to almost all music for free. It doesn't matter where you find it, myspace, Last fm, iLike, rapidshare, yousendit, youtube or torrent.. it's online. In other words, where else would you share your music?
