Is that Tyson tries a little too hard to be funny. Not clownish funny, but enough that
while he may be trying to appeal to the masses, he may instead end up not being
taken seriously by either the public or the professionals.

His latest Nova ScienceNOW on PBS was an example. The series already is being watered
down, and now they're doing what Tyson himself called Nova for the short attention span
generation.

Sagan was often wryly humorous, but he didn't pander to the masses. He let Carson
be the clown for him.

I wonder if in this digital media age there will ever be a single spokesman for science
again? Maybe it isn't necessary, so long as we don't expect across the board quality.

Maybe I'm just expressing myself from an earlier generation.
