Ugh. This decision is not as easy, nor as black-and-white, as it can seem. Personally, I'm very torn over this one: There are very good reasons
to include it, and very good reasons
not to include it.
What can I say? Everyone here, on both camps,
is right: on one hand, it can dilute the quality of discussion, and "dumb it down". On the other hand, it is a positive tool for acknowledgement of something without "side-tracking" the main discussion. Both points are true. We have no "right" or "wrong" answer here based on technicality alone.
You have to really screw a conversation to have no likes.
No. A conversation or, to be more precise, thread comments can go without a "Like" also simply because of not many people reading the thread, or the comment, even when you make a quality post or cover new ground that is, actually, appreciated. Another issue is that using "Like" requires a logged-in user, so even if you have your "admirers", they are "ghost admirers" who cannot express that they "Like" your posts. So @ssp3 actually has a point with that.
=====================
Personally, what I can say to contribute to this decision is
our history:
I think the "Like" feature was added sometime around late 2019, perhaps a bit before or a bit later. Obviously, the forum functioned perfectly well without it for all this while.
When the "Like" feature and button were finally introduced, I feel as if it was mostly well-received, silently, and well-appreciated. In general,
I think it brought more good than harm. Admitedly, I grew fond of it, as well, and I don't think it made
me participate less, whether my posts were getting liked or not. It
did make me show appreciation for people's posts which, otherwise, I would have said nothing in place if no "Like" system had been implemented. Of course, if there was something I REALLY liked, then I would say/write it, AND add the "Like" while at it (if the "Like" function is available).
So, in short, I think the "Like" feature served us well in practice, in helping us express ourselves a bit better, with minor drawbacks like others pointed out. Maybe we could have "misused" it, but from what I saw, it seemed to be used "correctly", unlike the braindead FaceBook et al. stuff.
Simultaneously... @Mat and the others are also right. It's really tough: there is no "right" decision, because we WILL have a tradeoff, be it one way or another. Which one is more worth it? I don't know.
But what I DO know is that
we will be fine eitherway: we were fine before it was implemented, and we were fine during the time it was around, as well, so my conviction on this is 100% unshaken.
So I honestly leave this decision to all you guys, and you can count me as "neutral" on this. Maybe I slightly lean towards having it back, but honestly I'm completely fine with it eitherway. It's not that "I don't care", as the poll suggests, but rather "I care so much that I know we are fine eitherway, and there's not one uniquely-correct choice".
TL;DR I voted on "I don't care.".
