I've just asked a question and decided to tag it "grid-typesetting", having a vague feeling that the "grids" tag is not a best one here. Soon lockstep edited it and changed "grid-typesetting" into "grids". While I'm fine with this, I decided to check whether my feeling was right, and I think yes: the "grids" tag is used both for graphical things (usually with tikz) connected e.g. with different coordinate systems and for grid typesetting.
There's also an "ltxgrid" tag, but this is too narrow - ltxgrid
is probably not the only way to do grid typesetting in LaTeX, and there's ConTeXt, too.
So: what do you think? Is a "grid-typesetting" tag needed? (If yes, I could look through the questions tagged "grids" - there are not too many of them - and retag them accordingly.)
