I've already shared early version that wasn't launched yet. Now I fixed some things and it's ready to be used. I have recreated a few posts from HN just to show how it would look like. In short it is:

Web chat

Anonymous, no registration

Channels and threads, each thread is a real time web chat

Enter name and if channel is not taken it's yours

Easy upload (mp4 only and 8mb limit for now)

Old content periodically deleted, but since few users for now it's on hold

No upvote/downvote system

4chan style reply system.

It was implemented with meteor.js
