It has become apparent that this medium of political discussion/debate/news-sharing has an advantage over talk radio and news TV. Regardless of political affiliation, using the web instead of the radio/TV allows the listener/viewer/reader to employ a much better BS detector/filter, especially considering the locations both forms of communications are used.
Wingnut radio/TV, as with all radio and TV, is essentially one way communication; sure you can call in or write-in, and if you've found enough four-leaf clovers that day AND the hosts/station are mildly agreeable you might get some airtime with which to point out mistakes (lies) and so forth. I'd bet that the bulk of talk radio is listened to while driving, which further complicates the dialog that can take place (it can be hard to drive and debate politics on your cell-phone, especially in Southern California traffic).
Also, if you're stuck in a car and some crazy AM radio type spouts something completely insane, you have pretty much zero options to check the accuracy of their statement. You're only hope is to probably wait until you get somewhere with internet access. This can make BS detection/filtering of anything via radio/TV very difficult; but don't panic, jump the fold!
If you read something on the internets that makes you do a double-take, you have seemingly infinite options at your immediate disposal to determine if the given crazy statement or new story is legitimate. It is this aspect that keeps the online community generating AND editing night and day; hopefully in a drive towards truth, but sometimes in a drive towards covert disinformation (spurious wiki editing). We have a responsibility to remind others that a community this large and inclusive puts an enormous amount of blood sweat and tears into getting it right.
All of these faults with anything more than raw, unfiltered news delivered through radio (and to a lesser extent TV) help to keep a lot of the American electorate rolled up in the lies that the red team is selling them. I'm sure a lot of these points seem obvious to some, but I think this is good ammo the next time someone asks how you can get some of your news from "that hate-filled Nazi website?" You can say you'd rather check your facts, than take King Loofah on his word (not that any of use would watch, but I imagine there could be one or two masochists on dKos).
Make sure to remind anyone that only gets their news from print/radio/TV, that online they CAN a voice. Instead of leaving their voice to the mercy of whatever corporation owns the particular paper, magazine or station. As I said before, this should be obvious to all of us, but sometimes we forget to remind other people about it.
Just trying to put another grain of truth on our side of the scale.
