size of XQuery developer community

[Daniela Florescu]

Dear all,

almost every time when I give a talk about XQuery I get confronted
with the same  question, to which I do not know the answer.

The question from the audience always is: " How many XQuery developers  
are there? "
-- with the underlying assumption that, indeed, there are not that many.

Please help me with this. I honestly don't know the answer.

How do you appreciate the size of the XQuery developers community ?  
(thousands,
tens of thousands, millions !!??)

Thanks in advance, best regards
Dana
