Yea i can't decide whether it'd be easier to have a refined widget of what i current am proposing or if i remove that and use a simple "star" system. So create a Tab at the top that says "Favorites" or Followers with a "star" icon. Then create a Tab at the top that says "Tags" as well. Then create a mechanic that allows you to star a tag in the tag list and star a follower when you access their profile. This way when you go to each tab it would display content that is dynamic to the starred tags and to the starred followers. To turn them off you could unstar them in the post feed at the post level or unstar them in their profile view. Same with tags on the home page logged in, or on your "my blog" page.
Im leaning towards scrapping the whole top 20 idea, and just allowing a user to clutter up either tab as much as they choose and eliminating the widget for lean ux and easy usability... Thanks for your comment btw, and the resteem very nice of you. I added you and tried to reach out on discord but couldnt get through.
