I've seen enough of your not so trivial proofs to think you're a professor and noticing the topics to which you most often reply, I'd say your speciality is set theory.
What do you consider difficult? Every GO space is a subspace of a linear ordered space; complementation of the lattice of topogies; Rudin's theorem that a space is compact, monotonically normal iff it's the continuous image of some compact linear order space; space filling curves; Brouwer's work?
Anyway, your replies have been enjoyable for their mathematical excellence.
