TypeKey is the next generation of commenting on blogs. Basically, it’s a centralized blog commenting registration system — one registration and you can comment on any blog that leverages TypeKey. Officially, “TypeKey is a free, open system providing a central identity that anyone can use to log in and post comments on blogs and other web sites.”
This blog will certainly leverage TypeKey once the service is publicly launched.
I already have a TypeKey account since I’m alpha testing Movable Type 3.0. The cool thing is that since I did beta testing for TypePad, I didn’t even have to register a new account for TypeKey; my TypePad username was already converted to a TypeKey account for me.
Anyway, I can’t talk yet about the features of MT 3.0, but it obviously leverages TypeKey, which will be an awesome way to limit comment spam.
Exciting stuff is afoot in the world of blogging.
