McCain Campaign Using LinkedIn

This is one of the best uses of the native feature set in a social media application I've seen from a campaign yet. John McCain is leveraging the questions feature in LinkedIn to invite participation, ostensibly from an "expert" set of individuals. Given the LinkedIn usage stats, his campaign is onto something. I'm curious to see if they incorporate the comments here into the McCain platform or campaing planning.

I also wonder if either of the Democrat candidates will reach out in the same way, or if the demographics of LinkedIn seem too upper income business user for them to spend their money that way... which would be their loss I think.

UPDATE: John McCain does also accept LinkedIn connections (at least when politely worded) and wisely keeps his connections private.
