I mentioned this a couple of years ago, and I don't know if any work has been put into this.
Blog Notifications would be very convenient, instead of having to go to your blog every now and then to check for replies or whatnot. I think it would be a useful feature and I'm sure this was considered before but putting it back out there for consideration because it would make life somewhat easier.
I have seen threads before this giving the same suggestion and nothing has happened. It would just be really nice if you guys could add this, please! :3
