I guess nobody is going to explain this to me, because they think it’s weird I don’t already know!
I guess it just means what it says, “I like/or agree with this” . I got that for comments, but for the groups does that mean that if there are 98 members and only 5 hearts, does that mean the other 93 people don’t really like the group?
Funny, unless there's more to this I'm missing: When my students just respond with "I agree" or "I like that" I tell them they need to add some substance to their comment. I'd much rather hear some details about someone's opinion/experience than just see a heart added, even if they disagree with me it would still be more interesting!
