The more I use e621, the more desperate I am for a way to organize the artists, franchises, and general tags I enjoy in one place. The rate of new content being posted makes it difficult to browse all of it at once without missing things, and I have too many interests to search each one manually.
After spending a while searching the forums, I discovered the old tag subscriptions feature, which I understand was nonfunctional for some time before eventually being removed. I also found multiple subsequent requests for functionality that would be met with the tag subscription mechanism.
My first question is, why was it removed? Was it difficult to maintain, or was there low user interest? Since personalized content feeds are a central feature of so many other modern websites, I don't see an obvious reason why e621 is an exception.
Second, are there already any plans or decisions regarding this feature? If the devs have specifically decided against ever re-adding tag subscriptions, I can accept that. Conversely, if there is already a plan to add them, I would be thrilled to wait patiently for it.
Two more points: If added, I'd like to request this feature be available to all users, rather than just privileged accounts as it was before. Also, I'm aware that some third party tools offer similar functionality, however, platform support is much narrower for those than a native site feature would be, particularly on mobile devices.
