COMMENT NOTIFICATION?

Is it possible, or is it in the works, to have some sort of notification when someone has commented on your game, blog, image, etc? It can be sort of inconvenient to have to comb through your images, for example to see if someone left a comment, or to address a question that you just found, but it's 4 months old.

In relation to that, is it possible to enable some sort of option to 'follow' the flow of conversation on a blog post, or something, to notify you when another comment was posted?

The second one I can go without, but the first one, I'm dyin' for.

Thank you!
