The same exists on nearly every social media site, sadly. Natural progression I would assume. On Twitter, in dev circles, we have "Junior Dev Porn" where the same poll/questions are asked, the same anecdotes are recycled, and the same code snippets posted, all in the name of empowering junior developers. But at a high altitude it's glaringly obvious the majority are for engagement and follower gain. Especially so when those internet points are leveraged for favor.
