[theoretick]

I have sat on organizational committees and name-blinding would not work for some of us for one key reason: We use speaker's name/identity as a criteria for talk selection. Two main examples are whether they have presented before and how "strong" of a speaker they are.

We DO use names to discriminate but that often allows us to have "fresh" speakers and keep the lineup somewhat varied. It also allows us to filter for all the other spam-talks; i.e. marketers.

It is an issue of priorities but I would easily place quality of presentations over guaranteed blinding to prevent gender-bias selection.
