To start with, most people are here to read TMO. It is not immediately obvious that talk.maemo.org is different from everything_else.maemo.org and that you need two accounts to be eligible to vote. That alone is an unnecessary complication and one thatmalmost stopped me from voting the first time. Why is it so difficult?
Another thing. You say 1.5% of those eligible to vote bothered. Is "those eligibile to vote" the same as "the number of invitations sent"? I would normally assume yes, but with the two accounts absurdity, I no longer assume anything.
