I believe that this year at YAPC Europe, we had the first fully (unpaid-up) conference widower of any European YAPC.
Tara attended, and gave a fascinating talk on manuscript genetics. But this year, her husband Mike was in Lisbon, but not attending the conference. (Previously, in 2007, it was looking like he was going to be a widower, but he ended up attending in his own right after a fellow employee was unable to attend, and he took his place.)
So, I'm wondering, is this the first conference widower of any YAPC? Or is it a more common occurrence than one might think?
