Billed as Twitter for comments, BlackType is the new kid on the block for following others comments and for others to see where you are commenting.
I'm taking it for a spin. As I understand it, now that I am registered, every time I comment on a blog, and fill in that comment form with the address of my site, BackType collects all those comments together, and you can follow me on BackType here.
This means I and others have one place to view all the comments I am leaving, and where I am discussing. Also it allows me to follow others, like twitter, and see what discussions and blogs they are posting on and in.
Back in early 2006 I wrote this piece about one of the problems of blogs, how they repeat the communication process they long to break, of one megalomaniac speaking, and everyone else listening, with a few acolytes getting to take part.
I linked to co-comment at that time, but it requires a plug in which was one step too many. BackType is much easier, and looks very promising.
You can read an in depth piece on BackType here.
All I need now is an application that parses this with twitter and facebook.
