Bill was mumbling AND thats how Bill talks AND it was a poor connection.
Not a dialect- but usually the complaint is that I talk to fast, not that I mumble. Might amount to the same thing.
On a different note- Phone is diff than in person since you can't read visual cues from the other person. Maybe we'll try a video and phone hookup next time.
On the topics of jobs and the size of the community: Many advisors at the better departments (where most theory reserachers are trained) do a poor job preparing their non-star students for the job market at the not-so-good departments where they will eventually have to find employment. In the less-than-good departments, theory candidates often have to compete with systems candidates, and the academic depth of their research is but one consideration. I know we have lost opportunities to hire theoreticians because of this.
