what was the first ever thread?

[codswallop]

anyone know?

And who started all the ds dd stuff?

Oh God in the early days it was just intellectual threads like the politics of breasfeeding or women's rights, etc, no chat areas or anything like that...

DS and DD came, I believe, from Usenet conventions -- the original Internet places to chat. Probably predate WWW, though I'm not sure about that. Try Dejanews and search for misc.kids, misc.kids.pregnancy, etc.

no good
