My question Who is Sifter, and what is “the so-called Sifter flare” exists only because the linked BBC news item wrote "Sifter flare" where it should have written Seyfert flare.
The BBC News article has since been fixed, so "Sifter" no longer appears anywhere, which makes me wonder if I should just update my question to read
Who is Seyfert, and what is “the so-called Seyfert flare”?
The change might make the question and its authoritative answer appear in more searches which is a good thing, and a search for " Seyfert flare" shows no other posts that it could end up being duped to.
I can't think of any reasons not to update the question, except that it makes my reference to a previous BBC error about the colliding of "large hadrons" less obvious. (They edited once but there are still two references to the collision of large hadrons with other things).
