Thank you.
I want to talk more about anonymity. I take the point you made to Mr. Barrett about it being sometimes quite necessary. I would also like to suggest to you that perhaps there could be a user option on the account to authenticate or not, and then there would be a flag that shows up on a tweet that says whether this person is authenticated or not. That might help because I do think anonymity is a factor in bad behaviour online.
I would also like to include in such a mechanism the prospect of pseudonymity. I think that in a case where you have people who are operating in situations where they don't want to identify themselves to authorities, such as authentication authorities such as VeriSign, that there's room for a relative authentication mechanism such as webs of trust, such as PGP offers, so that groups amongst themselves can identify themselves among themselves and use whatever names they like.
That would be a very great thing, I think, if that could be arranged.
I'm not sure if the second part of that fits the Twitter paradigm. I'm thinking more in terms of Facebook. It would be nice if interactions could be filtered based on whether or not people are authenticated or not, relative to my web of trust, perhaps, or relative to a white list of authentication authorities, perhaps, or not on a black list of authorities. Is that something that Twitter might be able to contemplate?
