Yes I meant by changing text to Follow and placing Follow buttons instead of stars. If I take a simple example, How does it sound that a users favorited another user?? I feel it awkward as people are not favorited instead they are Followed. So now if we make two different systems, one for users and another for qeustions, categories and tags then that would be even more confusing. So its a suggestion to change complete Favorite to Follow. And if possible then some development in relation to Follow system can also be done, like
# Number of followers for a user.
#At the time of registration some recommendations can be done to follow a category or tags.
Even more can be done with Follow system, but favorite system is just not that appealing and non of my users are using it. So wouldn't it be better to change it to something which is better and users can be attracted towards that.
