It's happened quite a few times. Here's a recent one. So I'm wondering, what is the scenario? Are they scrolling down to the link of sites, clicking meta and posting? Are they googling for some result, that gives them a post on meta and then they ask?
It's revenge posting from that side of the fence.
For far too long they've had to deal with their share of closing and shunting questions such as "What is Stück Überfloé built with?" and "Why my question closing?" as not programming and "Belongs on Meta" questions.
They've soldiered up some pawns into the front line to ask programming questions that belong on SO on Meta. They know full well things get stuck here like the veritable black hole of no escape. Velcro could only hope to stick like this.
It's utterly, honey rhythmically scrumptious and delicious to their tastes and delight.
In this question, the OP said it was because the question was too subjective for SO
