There's a big difference between explaining something unprompted, assuming they don't know, and explaining something because someone asked. The humor here is comes from many people are excited to explain and don't check my profile. I don't think negatively for someone giving a sincere reply to a request, many are nice!
Meanwhile, here it's meant to be more performance art, especially to reflect what it's like when I *don't* ask and get told. Thanks for participating!
