It’s the etiquette question of the age.
Vote now, or forever hold your peace.
If you have to ask then probably not. I’ve seen it used to humorous effect in a very, very small number of circumstances.
When my sister first started doing Facebook, she liked all her own posts. My brother pointed this out to me and we had a laugh. We still chuckle about it, she still defends it (although she stopped doing it).
The people who do it seem to be the same ones who laugh so hard at their own jokes that they can’t finish telling them.
I wouldn’t, but I can see doing it if you have a particular post you want to give some impetus to, (I assume Facebook’s algotithm give your like on your own post the same weighting as if you’d liked someone else’s post but I don’t know)
Yes. I like the ones I post about other people or that have others in them, because I like those people.
The ones I post just about myself, no I don’t.
If I didn’t like them, I’d delete them, so it’s redundant.
“Liking” your own post increases the visibility of said post to more of your friends. I think it’s dumb but sometimes do it in order to get help on a monster. In the Golden Olden Days my game friends would have seen my post without my having to do so.
I don’t “like” my regular statuses… if it was neat or clever I will get “likes” at some point.
I consider it crass. As Ethilrist mentions, if I didn’t like it, I wouldn’t post it. But on a deeper level, really liking a post doesn’t necessarily mean that I like it, it’s more of an acknowledgment. If someone makes a post about having a bad day or a family member passing and it gets likes, it’s not that people like it, but rather that they acknowledge and/or agree with what you’re posting.
Still, it’s crass because it inflates the likes of a post. Sure, it’s only by one like, but when posts get only a few likes, that can make a difference about whether or not it shows up in my feed. In that regard, I guess it makes some sense if it’s something really important, like a birth announcement, a death, an engagement, etc. because those are things that are generally going to be important to most of your friends and they’ll want to see. But if you’re liking a joke or a share or something, you’re just flooding my feed more than it already is.
Frankly, I’d rather people not be able to like their own posts, and maybe let people mark something as “stuff most of my friends probably want to see” with some sort of periodicity, maybe once a week or something. If you have enough important stuff going on that you need everyone you know to know more often, you probably either need to allow followers or just go to another form of social media like twitter or instagram instead.
And personally, I generally only like things if I want to acknowledge them and I don’t really have something to say more substantial than “me too”. I will like and respond if I think something is particularly interesting or clever, but that’s rare.
Seems a bit pathetic and needy to me, so no.
It’s the virtual equivalent of applauding your self, which is equally as gauche.
“When you “Like” a post, that action is noted in your friends’ ticker boxes, giving them a chance to at least be made aware that you have posted something even if it doesn’t show up in their news feeds.”
Yep, it’s all part of Facebook’s algorithm.
Whether or not you think it’s crass, liking your own post boosts the chance that your post will show up in your friends’ feeds. I’ve done it. Many of my friends there have and still do it. It’s no big deal, tbh.
I get how it raises visibility, but it generally seems tacky to me, outside a very specific jokey context. You don’t high-five yourself, unles you’re Tina Fey. And you’re not Tina Fey.
I get that.
When I learned of this area of their algorithm I experimented with not liking anything I posted, just to see what would happen. Turned out a lot of people on my feed never saw any of my posts. I don’t “like” every single post I make, but I will “like” those which I think will elicit conversation. Many of my friends there do the same.
The more “active” your feed the more the algorithm will show you on your friends’ feeds. It’s as simple as that and nobody, at least in my corner of Facebook, makes a big deal of it :shrug:
Hey, somebody’s got to “like” my posts. 
It seems kind of arrogant. What someone has to say is So Important that not only do they have to post it in the first place, they have to make absolutely sure to get maximum exposure. On things like amber or silver alerts, etc. it’s fine but on regular posts :rolleyes:.
Better than shouting into an empty room, so to speak.
It may be that I’m just an old fart ( I am), but I find Facebook and Twitter and most social media to be vapid, pointless, narcissistic pablum, eagerly granted importance way beyond its measure by a compliant, lemming-like demographic who mistake popularity for importance . YMMV
No. It’s a silly thing to do. It’s like laughing at your own joke. If I didn’t like what I posted I wouldn’t have posted it.
Seriously, what does this have to do with the question actually being asked?
