ppipes: e-mail aggregation for liberals

Linklogging about Zack Rosen: he has started up Progressive Pipes (ppipes) to aggregate e-mail news from liberal causes, campaigns, and candidates. (Earlier PoM entry about Rosen’s plan to build groupware and other development for nonprofits is here.) As Outlandish Josh put it, “Juggling 33 progressive mailinglist subscriptions so you don’t have to.”
