Somebody should start a poll:

Facebook + Email + IM + Phone vs. HN + Email + IM + Phone

Which would you rather have?

I suspect this would provide some valuable information as to the near future of the internet -- so many of us are on HN because it is specific to our current interests -- whether hobby or professional -- and our desire to know and bounce ideas off of similar minds.

Now for specific interests replace HN with (Popsugar, TMZ, Social Investing sites, etc.)
