Similar to the context of "The tag 'units' and us", I came across the tag size, through processing a review queue1. Ultimately, I initially meant to use this tag, but a bit of investigation lead me to the assumption that I probably shouldn't.
This tag does not appear to have been brought up in meta, previously, but it appears to suffer the same problems we see with the tag units: the tag receives little attention, and when it does, the interpreted context of "size" appears to be mixed.
What should we do to improve the quality issues concerning the size tag?
1In not exactly the same context, of course, but I digress.
