Change is afoot! In the list of all users ranked by reputation.
I've been #1 in that list, the highest-reputation user on Puzzling SE, since early 2015. But it seems the time has finally come to give up that position and succumb to the relentless rise of the Gareth.
Mr McCaughan joined Puzzling SE in February 2016, having already been a member of the Stack Exchange network for several years previously. His rise to the top didn't seem meteoric at first, but he quickly made a name for himself with his wide-ranging skills and formidable puzzling talent, both in mathematical/logic-based puzzles and in more wordplay/language-based ones, with the help of his background as a mathematician and his vast general knowledge. By the time of Puzzling's second moderator election in 2017, he was a clear candidate for a runaway victory. Since then he's served very sensibly as a site moderator while still continuing to solve puzzles.
While losing the top spot in the reputation leagues isn't cause for celebration for me, there's no doubt it couldn't have gone to a worthier successor. I'd hoped to be the first user here to receive a 100k swag pack from Stack Exchange, but now I wish Gareth the best of luck in beating me to it.
And might I suggest celebrating this occasion by posting a question? If you've been waiting for the right moment, Gareth, then surely becoming #1 user is it. And no, a CW repost of someone else's question doesn't count :-)
Finally, don't worry, this isn't a retirement announcement. The "end of an era" in the title refers to my 4-year stint as highest-reputation PSE user. I'll be sure to check back in 2023 to see if Gareth can hold it for 4 years too ;-) but in the meantime I'll still be here and posting away as always.
