A3M - Account Authentication & Authorization Module

Hi, sirwan.me. Nice article. Let's make A3M better than the rest ;-)
First, I'd like to correct the link I posted before. THIS is the article on User Experience. Very interesting, and I'd like to discuss its view here.

Let me explain my point of view: I'm not against Username as log in, but it cannot be the only one. Give some hours to write a whole explanation. Meanwhile I'll write brief description.

Username is good for memory and people who don't have email.

But let's face the future: we have Facebook, Twitter, Gmail Connect... all of them try to make us write our social profile on them. Then, why make the user write again his username, while we could have not only his username (for posts/comments/profile) but his gender and language to send him emails through only ONE email?

I hope you see the point at least (I know you won't share it so far, but at least know what I'm trying to say)

We should face situations like "I changed my email on Gmail and now I cannot access your website" or "I lost it and I'd like to log in to your website while I recover it from Gmail recovery system".
We cannot focus on one static way. That's the past. I'm angry because every forum I try to add to my website don't have native ways to user Gmail/Facebook/Twitter accounts... Let's build for the future, not the past.

Please give me time and I'll (try) to post a whole bunch of situations (username/email remembered/forgotten/lost/changed)
I'll "speak" to you later
