-) vtipny napad, v povrchnosti sa podoba prave tejto posthistory - pri nej autori tvrdia, ze pri merani komunikacie dnes nie su ani tak dolezite obsahy ako hlavicky mejlov - od koho, komu a subjekt: "All of the analyses in PostHistory happen at the level of message headers. This means that PostHistory has no idea of what is being said in any of the email messages it looks at; it only knows that people are talking to each other." samozrejme druha vec je, ze si len potrebovali stanovit zvladnutelnu sirku zaberu a obsahy boli lenivi analyzovat -)
