Feature Request: Subscribe link category

[PeterHKK]

Our website will have many link categories for different readers. For example, programmer, designer and marketers. If our users can subscribe link categories only what they concern about, it is easier to read links by simply click on My Subscribed Links.

So, I expect there is an extra option within Links of User Menus. For example, let's say My Subscribed Links. After opening My Subscribed Links, user can select which categories to subscribe.

On front page, there is an url, My Subscribed Links, near the All Links.
