If your a mozilla user it should autoplay. Look for an audio player on the listen page. It should look like the normal mozilla player when you click on an mp3 file. Also, guys, I added a remember me feature to the login screen, which a lot of people scemes to want, so yay!

I think on youtube you do not have the option to hide your username. Do you want to hide your own channel? how's people gonna find you?

I just put up weird crap I made in goldwave up there from time to time, the only downside is if its something that is only a second or two, like a notification you could use on your phone, it won't let you upload b/c of the 50KB limit, but I get why that limit is in place.

It would be good to have easier access to the time scrubber and volume controls of the player, but that I think is just the standard HTML5 player, and I don't know what all you can do with that from a development point of view since I am not one. I do know I have been to sites with a very good player and been to sites where you can't pause or anything like that. Now that most platforms are using HTML5, or are working on rolling that out, things are looking up for accessible audio and video players.

Um... sorry for getting off topic.

One thing that would be cool is twitter sharing. Yeah sure most people don't use twitter for web anymore, but could be nice for iOS users and just to have there.
Here's the thing from twitter support that explains the steps.
