As toomanykooks has been looking for it
For starters I just discoverd this new Personalised Podcast feature which i'm yet to try but this sounds incredibly interesting. The new colour scheme shows it as perdominatly white though it's similar, it's much easier to navigate from chart to chart and the is now a friend update thing on the right telling you what users have done what recently... if someone goes on your page, like facebook it will show you the actions said person has done.
It's easier to see the inbox and charts update in real time in essence it's just all a lot cleaner.. but for some reasson it does give me a bit of a headache but I have seen drastic improvments already DESPITE only using it for a couple of days... plenty of bugs and layout issues seem to have been fixed since.
So yea it's more like facebook, expect to see many things on a singular page as opposed to the clunky flicking from page to page on the old last.fm
