Willing to vote for Quester too, to rename the Mozilla Firefox browser. Internationally Quest is clear enough (Police Quest game, ...), and -er is a common suffix (play, player, game, gamer, ...). Even in cases the word Quest or Quester doesn't exist in another language. The urbandictionary.org output seems to be safe too.
Quester, possibly also stylized as QUESTER, is an existing (commercial) name in several of the countries of eCS x.y languages. As suggested earlier, perhaps insert a "Qanadian Quester (Quester)" in a main README.1ST to point out to the owner of quester.com that the domain name qanadianquester.com isn't/wasn't theirs and that the formal Qanadian Quester is a unique name. Or Canadian, if SM's new name won't start with a Q.
The wizard of the latest images does look better than the Dutch Flipje's (Lil' Phil's) grandpa. Hopefully the 40x40 version of a winning icon still looks good too.
AFAICT a looking glass may not be what international users expect what it is (a loupe or magnifying glass, if the icon looks like a loupe/Lupe/loep), and presumably you'd use a looking glass to look at yourself. YMMV.
