Are blogs like tulips?

Here's someone who thinks blogs are a fashion item .

William Powers, in the National Journal, says:

the market is in love with a bunch of little start-ups that weren't even around five years ago. Bloggers, one-person media outlets, are the hot darlings of this feverish moment. Like the New Economy stocks of the 1990s, these newcomers are sharp, energetic, and fearless.
