After Tuesday's poll looking at which network providers will be buyers in 2011, several readers suggested a followup poll looking at the most likely sellers. As it happens, I had already anticipated that suggestion but didn't want them to run the same day. I also decided to give some different polling software (PollDaddy) another trial. Those of you who found Tuesday's poll to be broken for a while that morning, it should be all fixed now so go back and have your say! I'll give my own take on both questions next week.
