everyday-chemisty is a useful way for people to find questions that laypeople might ask about chemistry. It's a bit of a "meta" tag but we can hold (or re-hold) that discussion another time, since I think it does have some utility.
It gets abused by new(er) users thinking that it means chemistry that is "ordinary" or "commonplace" or "textbook", etc., despite having a half-decent tag wiki.
So, if you see this tag on a question where it doesn't belong, please edit accordingly. Please note that this is not an invitation to untag every everyday-chemistry question but just to refine the set we already have for the time being.
I realize that with the site graduation, many of you have lost the ability to edit (with the rep requirement being 2K rep now instead of 1K), but we are very efficient at approving/rejecting, so don't hesitate to put suggested edits to good use.
Geoff has suggested providing some examples: (note, these are all in my opinion, and what I hunted down with a cursory glance, so any input on these specific examples would be great)
