1. (noun) any content on the internet whose humor derives from its surreal nature and/or its lack of clear context. Differs from a meme: whereas a meme's humor comes from its repeatability, a shitpost is funny simply because it isn't a predictable repetition of an existing form. Shitposts can become memes, but memes cannot become shitposts.
2. (verb) to create such a post
No idea where you're citing. Oxford gives me "a deliberately provocative or off-topic comment posted on social media, typically in order to upset others or distract from the main conversation", which fits my usage perfectly. You'd agree this framing is "deliberately provcative", no?
Wikipedia explains it similarly: In Internet culture, shitposting or trashposting is the act of using an online forum or social media page to post content that is satirical and of "aggressively, ironically, and trollishly poor quality"; it may be considered an online analog of trash talk.
Even Urban Dictionary is on board: A post of little to no sincere insightful substance. Especially a "shit"(low)-effort/quality-post with the sole purpose to confuse, provoke, entertain or otherwise evoke an unproductive reaction.
Frankly I have to assume you went out of your way (like, off the front page of a Google search even) to find a definition that you could cite just to prolong an online argument. I wonder if there's a word for that.
None of those definitions fit the original blog post. It's not satirical or ironic, it's not aggressive, it's not trolling, it's not off-topic, it's not even a "comment". It's not poor quality (imo). It's an opinion piece.
My definition was from urban dictionary btw, the first entry, maybe it sorts differently for different people.
"Google is Attacking The Open Web!" is 100% aggressive. Whether it's trolling or not depends on how people react to it and not its content per se. And here we are in this ridiculous subthread. So, yeah, it was trolling too.
Come on. I repeat: it's a complicated subject and a real problem, and a sincere but potentially flawed proposed solution. It deserves serious discussion and not a bunch of yahoo's throwing bombs about the evil corporate overlord of the week.
