In Stack Exchange portal, it says:
Stack Exchange is a fast-growing network of 112 question and answer sites on diverse topics from software programming to cooking to photography and gaming. We build libraries of high-quality questions and answers, focused on the most important topics in each area of expertise
Emphasis is mine, note the "high quality".
Now, have a look in the Hot Network Questions, visible in the front page of every Stack Exchange site:
That's not high quality. For the occasional visitor or 99.999% of Stack Exchange users, this is useless nonsense. Only going to the the tag wiki on the site itself will reveal:
Note: This is a code-trolling question. Please do not take the question and/or answers seriously.
OK, let them have a party but I don't want it to overflow to the whole network.
Can Programming Puzzles & Code Golf site be excluded from the Hot Network Questions list until this party is over?
Edit: and they even invaded this very question!!1
