Philipp, I think OpenID is something for you :P

http://openid.net/

You could even extend it a little so people can specify an 16x16 icon on their own profile/site (which you can automagically grab).

i would agree, since i'm always paranoid someone will post on Blogoscoped with my name by just typing it in and abuse it.

Philipp, any plans for authentication in the future? i don't believe we've seen others imitating other people's post, but then you should know more than i.

I'll keep an eye on this, thanks guys.

Wow! OpenID sounds like a cool idea overall.

But for Google Blogoscoped I love the lack of password / login. It creates much more of an atmosphere of trust.
