Before you email me:
Did you find a nice blue page about some obscure topic? Did you find yourself thinking, Ah-ha! I can ask her about this!?
You probably found a page in a topically-augmented clone of Wikipedia linked from my website. Your blue page was automatically generated and I am probably no more an expert on that particular topic than I am on stellar classification, the town of Ettrick, or Mickey Mouse.
That said, if you want to email me about topic models, recommendation algorithms, visualization, online inference, or anything related to what I actually do*, please feel free to do so.
*Computer-related stuff outside my areas of interest doesn't count, since the breadth of that is immense.
