Consumers of Stack Overflow content may not feel this way, but the developers who are engaging, commenting, and answering are being “lectured, down-voted, and leave with an empty feeling of wasted time.”
Constantine Murenin, writes in this OpenBSD mailing list thread:
The StackOverflow company routinely deletes your comments, questions and answers, often for very superficial reasons (including automatically based on metrics) and without any regard to the individual quality thereof, and effectively without you having any control over the explicitly human-generated textual data that you entrust them with. (Most folks don’t even know this, until they’re already hooked and their questions/comments/answers are gone and unfetchable.)
Who likes their own well-articulated notes randomly deleted for superficial reasons behind their backs? Why not let you see what got deleted, so you can decide whether it’s worth reposting in another venue?
The content you contribute to Stack Overflow is not guaranteed to be long-lasting immutable content. To dig deeper, click the headline, read this tweet, and read this post
