CommitteeCaller.com uses open source software to let you call every member of a congressional committee in sequence. In this day of email communication, I'd wager getting a phone call from an individual has a little more weight. Some additional pondering: - On average, how many individual phone calls from constituents does it take to equal one meeting/call with a corporate lobbyist? - What carries more weight when received from a constituent: a phone call, a typed physical letter or a hand written letter?
