Credentials & usernames - how about something people will remember for once...?

One particular issue I take with many web applications these days happens when they ask you to create a username for yourself to sign in to their service - I'm fine with creating credentials (though signing in with Facebook would be preferable), however what I don't like is when they get you to create some random name -- what really needs to happen is for these sites to force your login credentials to match your email address... this only makes way too much sense:

1. You know that there will never be a namespace issue, as every email address is by definition unique
2. People are much less likely to forget their email address, as opposed to some random username or tag they gave themselves when signing up for your service

Ultimately, if people want a 'tag' name for posts or some social aspect of an application they should be able to call themselves whatever they want... but for credentialing, let's keep it simple stupid!

Signing off for now,
