Suggestion to improve gmail labels and organize the email better

Background:
---------------------
I have figured out that emails of majority of people are from two kinds of sources -
1/ individuals (friends, family, colleagues)
2/ websites (registrations, newsletters etc).

The whole issue of organization of email is based on the separation of important/preferred emails (which for the most people(normal) are the mails sent by individuals) from the websites. For this same reason several people (including me!) create multiple email accounts to maintain the separation.

Suggestion:
--------------------
1/ To provide an option in settings/plugin (labs) to automatically sub-label the incoming email from the source and forwarding naked domains under the main  label of websites. (this will include emails from both individuals as well as websites and spam senders too!!) now as the mails arrive people can additionally label them according to their convenient labels too before archiving.

2/ Option to automatically direct the selected public newsletters to Google Reader from Gmail.

Advantages:
---------------------
1/ Proper tracking of what all sending domains have the recipients email address.
2/ A working spam filtration based on domains (though spoofing may occur but then the actual sender domain can be blacklisted).
3/ The perfect way of organizing the emails without ambiguity (and a way to add ambiguity by allowing users to add labels).
4/ The inbox remains clean.
