Johns Hopkins University Computer Science Professor Avi Rubin is a bete noir of the e-voting industry, having been one of the authors of a famous dissection of the security flaws of one e-voting vendor's machines (Analysis of an Electronic Voting System). He has been criticized for not knowing much about the actual process of voting, being an academic and all. So, to quench the ill-founded criticism and perform his civic duty, he volunteered to be an election judge for yesterday's ballot (though he had to make a great deal of effort - apparently volunteers are not encouraged). His insightful account of the experience can be found here: My experience as an Election Judge in Baltimore County. Extremely valuable stuff for anyone interested in e-voting.

However, Ed Felten notes that (Avi Rubin's Election Judge Experience):

It must be noted that the polling place where Avi worked was not typical. Everybody seemed to know in advance who he was. One of the other poll workers just happened to be an experienced Diebold trainer. Very senior Diebold executives just happened to show up before the polls opened to make sure everything was okay.
