Here is the [old room](http://chat.stackexchange.com/rooms/224/code-review) which was frozen due to inactivity. Here is the [new room](http://chat.stackexchange.com/rooms/2066/heapsort-discussion) which noone is ever in?

Why is that?

[This has been sort of asked before][1], but it was not completely fleshed out?

I believe that the chat system on this site could and will be very useful for people who want to review code.

Why is it not being utilized?
