answer:I think it’s pretty awesome, myself. There are approximately 46 Flutherites on last.fm (according to the Fluther group), and most listen to pretty good music. Not that that’s really important. I don’t believe there have been any viruses traced back to last.fm, mostly because there is very little content you download. There’s also a subscriber function, but it’s pretty cheap and free accounts will be good for 90% of what you want to do. However, to get the full experience out of it, it does help if you listen to music mostly on your computer or sync your iPod regularly. It will take the music from your iPod or computer and add it to your profile, which helps it to make recommendations for you. If you are only going to use it for the radio and not the social features, use Pandora instead. It recommends music a little better, and is a bit easier to learn. If you want to have all your music in one central place or stalk look at others music taste, though, I like last.fm. For the record, the Fluther Group is here and my profile is here. I’d recommend you check it out.
