Ben Adida says nice things about Google Wave. But I have to differ with
… follows the same trust patterns as email …
Wave most definitely does not follow the same trust patterns as email, that is something we have explicitly tried to improve upon, In particular, the crypto we use in the federation protocol ensures that the origin of all content is known and that the relaying server did not cheat by omitting or re-ordering messages.
I should note, before anyone gets excited about privacy, that the protocol is a server-to-server protocol and so does not identify you any more than your email address does. You have to trust your server not to lie to you, though – and that is similar to email. I run my own mail server. Just saying.
I should also note that, as always, this is my personal blog, not Google’s.
