I hope she has something bigger, better, and more exciting to move on to. She's well-respected due to her role in shaping Metafilter to what it is today.
As amazing as her work at metafilter is, it's only a small portion of why she's well-respected. In a sense, this is quite appropriate, and is why she's been so perfect as the heart and soul of AskMe, if not much of MetaFilter for the last decade.
I am incredibly curious as to what she does next, because I'm quite sure it will be both revolutionary and personable in a way that is rare and getting more so.
