Thanks for the comment onion2k - fair point. We definitely have a target market in mind with the app which is a younger demographic whose musical taste may not be completely developed just yet. Having said that, I'm sure you have a couple of friends you still turn to for tips on the latest and greatest?! As for favorites, again I'd agree with you but we've had a huge amount of interest from people trying to discover what sports stars are listening to before a big game etc. Social graphs are so subjective that this really is a binary type of idea. Some people will love it and use it a lot (hopefully), others will use other channels for discovery and stay away from the social curation side.

Thanks for raising this point so amicably though - I'll be sure to update the post with the links when we're live!
