So... I saw the bbq tag today... and was a bit mystified to see that apparently the decision was made to make the abbreviation "bbq" the primary tag rather than the full term "barbecue"... this was discussed early on in the site creation process here: which tag should we use [bbq] or [barbecue] (2010) and it seems that the consensus was to make "barbecue" the primary tag... but clearly that didn't ever happen because in 2012 it's mentioned in an answer here Should SA create an 'official' lexicon?
This answer seems to show that there were certainly more uses of bbq than there of barbecue but I don't think that makes it a better tag.
So, at some point it was decided to synonymize the two but I'm not sure why this was the direction it went.
Can we please reverse this and make barbecue the primary tag?
Could we please switch the order?
