Karl Brazier, Requests
I think the low showing (at the time of writing) for "requests" is a warning against over-reaction to opinion polls. While it seems to be on few people's list of favourites, I imagine most would agree with me that they would respond to any request that they could help with, that it provides a valuable service and that they wouldn't want to see it ditched. I'm sure I'll be corrected if I'm wrong 8-).
If I had the option, I would have said that the polls are my favorite feature... but of course that would present a bias in the poll itself.
Will Dwinnell, Datasets (re: Poll)
I only voted for 2 things: my third would have been the Datasets section of KDNuggets.
Several people also indicated that polls were the most interesting section.
