Follow categorization with filtered timeline views

Would be so sweet if @x added a feature that allowed me to categorize the people I follow based on the reason I followed them so that way I could refine my timeline based on the information I want to see at that point If I followed you because you are a great animator, I could add you to my animation category, and that way whenever I want my feed to just showcase those followers, I'd have the filter to do so @grok what do you think?
