when something going on live is simultaneously put on the internet through a site like twitter, facebook, or some other kind of blog; a simulcast online, using a close captioning without the video. typing news via text as a true "eyewitness news person".
I missed that part of the press conference because I was too busy simultyping on my blackberry. (or) I don't like when people simultype concerts on Twitter, and later on upload shitty quality videos on youtube of the concert. (or) Did he really just simultype that President Obama farted at the All Star Game?
