I feel like I'm pretty "old fashioned" about likes/favs on social networks, as I treat them like "good posts I'm bookmarking for later review". I treat network post faving like I do art site faving - it's something special.
By comparison, it feels like a lot of other people fav almost *everything*, encouraged by things like Youtube treating likes more like a meaningless quality meter for the creator, rather than an archive of high-quality content for the viewer.
UX musing.
@Thaminga @Taylor I also treat it this way. I don't always have the easiest time wording my appreciation for a thing, but I don't want to ignore things either so I do this as a middle ground.
