Qiaochu Yuan is top 10 on MathSE, but - due to his interest - mostly focused on abstract algebra close to higher homology theory and such. Might be good if he's in a more tangible field, assuming he keeps on being public and write on the web. I remember he also became part of the nCafe at one point, but I think he never wrote anything for it in the end.
