Friend List based on interest . This way Steemians cam easily find content or other Steemians that share the same interest. More like a Pinterest vibe mixed with Tumblr. Example...Pinterest send a notification saying based on your pins(post) or content repinned these Post/Boards/accounts may interest you.

Currently on STEEM I'm have to dig deeeeep for quality content that interest me the most and Authors I want to support blogs or .... but I don't have a buddy list easily accessible to . Hopefully your app can fix this issue .
