The idea behind Mixcloud is to connect independent radio content to listeners - a "YouTube of radio". We'd be very grateful for any constructive criticism via the feedback tab or simply feedback AT mixcloud DOT com.
You might recognise a couple YC-ers on the site (we're good friends with the guys from Songkick, Fuzzwich, Webmynd, Muxtape, Heyzap...)
On a related note, we were one of many young companies who didn't make it onto YC last year, so we'd like to take this chance to encourage everyone to keep building - whether or not you get on the program.
All the best,
Nico and Nikhil
