Peakd already has private favourites and I think Ecency does too now.
I used to like Youtube's feature of letting me promote specific channels on my profile page, which is similar to what you are asking for I think.
As I understand it, the PeerVerity protocol will make it possible to not only favourite a profile but to add detailed feedback and scoring of different aspects of the person and their profile too.
For example, one of my favorite Japanese restaurants is Ichiro Japanese Restaurant. Information about this business is already available on the Hive blockchain, and I can reference it in my posts. I can even follow them and receive Telegram notifications when other users post reviews about it.
But imagine if there were a heart button that would allow me to feature this restaurant (or any other business) in my profile, just as you mentioned regarding promoting channels on YouTube.
I can foresee an overlay over Google Maps or other such business maps that filters the restaurants according to whatever parameters you like, drawn from your network of friends.
"Show me the Japanese restaurants that John Smith likes in this City.. Or would probably like best, even though he hasn't been here" :)
Exactly. In fact, Dining.Gifts does exactly that - it displays all restaurants whose information is published on the Hive blockchain on a map.
Yes, you can filter restaurants by the type of food they serve and the amenities they offer. You can even search the map to find out which nearby restaurant serves a particular dish.
All of the data, including user reviews and sponsored rewards offered by restaurants in exchange for sharing two or more photos of their dishes, is publicly available on the Hive blockchain.
