Basically, talking heads and videos are a lot more striking than simple websites. The dissidents have (as usual) got there first with a couple of films posted online and/or in rare public viewings. This group of people have got together to create a series of counter-videos to either explain the science and medicine behind HIV and AIDS, or to counter specific dissident points.
Intentionally, their videos are titled to draw in dissidents, and apparently it works rather well :o)
This kind of work is long-overdue and should be applauded. As with this site and AIDSTruth, the work is pretty much done as a hobby, but what I've seen so far looks pretty good. Certainly a better job than I could have done!
