Both comedic sweatdrop and small sweatdrop are severely underpopulated even though they existed for a couple months now. The former only has 7 posts, with nonamethanks responsible for tagging 5 of them.
Similar to what Ubaldo the Uploader suggested, I propose we retag every small sweatdrop post to sweatdrop and replace the latter's wiki with the former's wiki. I think the "small" part might become a hangup for some taggers when the point is to distinguish realistic from exaggerated sweatdrops, not the size of the sweatdrops. This change will affect about 100 posts, so it's really a drop in the bucket when you consider the fact we have over 188,000 sweatdrop posts. We should also make an effort to populate the comedic sweatdrop tag so other users know it exists and actually start using it themselves.
I don't think this is as necessary, but it might also be helpful to rename comedic sweatdrop to sweatdrop (symbol). I imagine there might be some users that see someone with realistic sweat in a comical setting and think comedic sweatdrop would apply to it. Explicitly calling it a symbol reduces ambiguity and there is precedence with tags such as star (symbol). This would basically be the BUR in topic #20808, except I believe we should definitely not be calling these kind of sweatdrops emojis.
