I can already tell that discussion about coComment is going to be rumbling on for a fair bit. One of those things, it’s just seemed to have got peoples attentions.
Anyway, if your curious, I will be merrily tagging away anything I find pertaining to it at http://del.icio.us/brightmeadow/coComment if you want to keep an eye on that.
Ben Metcalfe has already written a great piece pointing out how coComment could lead to semantically forked conversations. He’s not being a nay-sayer, just pointing out that things might not be all as rosy as the hype makes it look.
