My comments/comment tracking
Just about to start work on the "My comments" feature which people have been after for a while.
Basically this is going to be a screen where you can keep track of everywhere that you've commented and it'll highlight entries where there have been comments since your last comment.
This will initially be a private screen just available to the user (any user…even if you don't have a blog yourself) but there will eventually be an option to make some of that info available on your own blog so that people can see where you've commented if you so wish.
The second stage to this is the feature where you can say that you want to keep an eye on an entry and get emails when there are new comments. Advantage of this is that it will help you keep track of places where you are interested in the comments, but don't actually want to comment yourself.
