Congratulations on reaching 100k reputation! We all appreciate the quality (and quantity) of your posts on Math.SE.
Brian, what more can I say than what others have said already?
I find your manner unassuming, warm and welcoming. You tailor answers to questions so well, showing both sensitivity to those who come here struggling and seeking help, and intellectual acuity when answering questions at a deeper level.
Users like yourself are one of the reasons I stick around!
From his user page:
I’m a set-theoretic and general topologist with an interest in combinatorics.
I myself am an aspiring combinatorialist with an interest in general topology. For this reason, I see Dr. Scott as a nemesis constantly thwarting my attempt to earn green check marks.
Kidding aside, thank you for your work here at MSE. I've learned a great deal about clarity (not to mention combinatorics and topology) reading your responses.
Brian, you're the best M.SE user I have ever seen! Your patience towards everybody on this site has been a strong point. I loved the day when you scrolled through my answers and complimented me. The site has been lucky to have such a genius. Good luck for being the first user to reach 200k!
After the history of MSE post, should we create one for the history of Brian M. Scott? :-)
And the first gold badge in Combinatorics on Math.SE goes to...
