I highly doubt that the intent is to have each post seen in people's timelines. It appears to be a place for constituents to "check up" on their representative in a way that is convenient and open. And I think that it's a bold cultural statement for a Congressman to make. I used to think that open and honest people didn't stand a chance in Washington, but that may be changing.
