I've not read their new paper but the first one was just ridiculous.
They drew an edge from A to B if A reassigned a bug to B and intepreted
this as "A knows that B is an expert on the subject".  That is just
ridiculous since A is usually a bug wrangler and B is to be found in
metadata.  For instance the emacs team which gets very few bugs almost
never appears as B (and certainly not A).  This introduces all sorts of
bias.  I think it would be fair to say that their first study had very
low predictive power and the effects they saw were created by their method.

Cheers,
Thomas
