yea i dont want to sort the content of lists by topic tag. thats not an interest. Being able to favorite a user ha or see what tags of categories they like or i like have value but sorting through a "my feed" by topic isnt really too valuable. Its not something globally usable really... Being able to sort between a toggle of resteemed content and organic content in a feed is enough. the average user isnt going to sift through a bunch of tags to find a topic written by a particular user.
