I can't remember a page/chapter of a work I'm subbed to that I haven't liked since I started reading here.
It's the perfect bookmark and it helps the author's visibility.
If a work is bad enough for any reason that I don't feel like click that heart button, I just unsub (maybe first I comment with the author to see what happened, but if their response is as bad as the update... I'll go )
What I'm trying to say is, are you proposing to do this inorganically?
People that's already used to that, will keep liking all the stuff they read.
Are you trying to attract to our like sect those that only like occasionally?
