OK, I regg'ed this domain: OptionalLogin .com.
I know it's not great, but I feel it's not terrible either.
Just for play, what would YOU do with this, if it were yours? (and please, I know lots of you wouldn't have got in the first place, no need to point it out!)
What about making a free portalpage at Aboutus.org, reporting about alternative login capabilities, by using an OpenIdentity, like OpenId, myOpenId and making it a platform for user experiences ... Or make it a specialized blog or a mixture of both ...
I like the idea of a site that can automatically log you into other sites. Since the social network fever is so high these days and there are a lot of social based sites that would be a good choice.
To tell you the truth, Netzilla, and Weblord, that was one of the first ideas that occurred to me. I'm happy some non-noobs (unlike me) would agree with that.
I fancy a bugmenot-like forum too.
I'll see.
If anyone has other ideas, just keep em coming.
