Where the ads aren't

Megan McArdle looks at the troubles with trying to get money from advertisers.
A main one she sees - companies don't need journalists to get to their audience.
But I think the biggest issue is the one that I hear the least about: Companies just don't need intermediaries as much as they used to. They can build their own Web pages, run their own videos on YouTube. Sure, they'd like to have our readers, but because our readers ignore or block their ads, maybe they should just put the money into building their own Web presence.
