Cool!  So, I double checked:

"prefer python to ruby"         21
"prefers python to ruby"                0
"ruby to python migration"              0

"prefer ruby to python"         260
"prefers ruby to python"                0
"python to ruby migration"              0

Judging on the "prefer" only, Ruby > Python > Perl.  Check:

"prefer ruby to perl"                   5
"prefer perl to ruby"                   0

Still OK, I guess.  So, my working hypothesis would be: people tend to
post about preferring a newer / less widespread language over an older /
more widespread one, more frequently than they post about the reverse
preference.  Why people compare Python with either Ruby or Perl MUCH
more often than Perl and Ruby with each other, I dunno...
