With Capitol Hill a ghost town as members scramble to retain their peerages, the lull in legislative activity offers welcome pause to step back from the e-mail deliverability fracas of recent weeks.

A great many of the unmet expectations and bad feelings that have become bundled up in online write-your-rep actions ultimately trace to the unspoken assumptions various parties have about the communicative framework in which the action takes place.

That point was underscored in the live chat with Washington Post reporter Jeffrey Birnbaum the day his column ran Capitol Advantage's deliverability study.
In response to a question about how to differentiate grassroots campaigns from astroturf, Birnbaum opined, "I'm afraid if an interest group incites a flood of e-mails, that's Astroturf lobbying by definition."
