So the word "meme" has been co-opted to mean "questionnaire"

Either that, or when people say "Here's a new meme", they are really saying "Here's a new [questionnaire] meme", because these "memes" tend to be a specific, new type of questionnaire.

At the risk of sounding like the incredibly nitpicky Englishphile Miss Em linked to recently--a person who apparently despises language change--I would like to point out that the word "meme" can be used for many things besides questionnaires.
