@quid: Thanks for pointing that out! I was out of the loop for a bit... I'll think of something to answer for Sébastien's question tomorrow. Fortunately, the tag usage hasn't spread beyond Sébastien, so it's easy to remedy right now.

@RicardoAndrade: IMO, index-spagetti is colorful but too culturally specific and perhaps prejudicial in some contexts. debauch-of-indices is just as wrong as the (fortunately non-existing) stupid-notation. I wouldn't necessarily mind a reasonable alternative but these two are slated for deletion.

@François Dorais, I do not know any good alternatives, yet I cannot disagree with the suggestion of deleting the tags related to indices. Also, I am definitely not crazy about the tag 'partially-answered' either. In my opinion, it serves a function that tags are not meant to fulfil.

Thanks @FrançoisG.Dorais. While we are at it could we perhaps remove current-affairs? It is on a handful of questions serving no actual (consistent) purpose as far as I can tell. In addition to what was current four years ago, might be not so current now.

@quid, very good catch with the tag 'current-affairs'!
