Members of congress communicating via twitter

Congressional 140 is the most complete listing of members of congress with Twitter accounts that I have found [as of October 2].

I think there are going to be many notes about this so I am going to set up an embedded search here.

I looked at the messages that Archivist would find searching for the twitter username. I started to take only the messages of the members of congress. Then I decided that I wanted to be able to treat this as 'conversation' -- at least some messages could be understood as conversation while others are just 'shouting'. So there are 185 collections that should be updated weekly.

A few more members of congress are taking on Twitter during the succeeding weeks and months.

The numbers by year are:

There are also 3 with 'protected profiles' so I cannot tell when they started.

The members who had few messages when I started have, for the most part, gotten many messages since the begining of the month.
