Usability group homepage is getting out of date: let's fix it

Problems with g.d.o/usability:

• Duplicated content: "Post by topic" block in main content are and "Group categories" in sidebar are 100% same, one of them needs to go
• Outdated information: Both "Quick UI review please" and also "We are working on:" sections in usability frontpage are severely out of date

New trends:
- important usability issues can now be found at http://drupal.org/community-initiatives/drupal-core/usability
- issue queue URLs have changed, they are based on views filters now, http://drupal.org/project/issues?projects=3060&components=usability&stat... link for usability component is dead link
- we have now tags in issue queue for identifying UI issues, "Component: usability" is likely depreciated
- very likely g.d.o is moving back under drupal.org umbrella http://drupal.markboultondesign.com/iteration11/community.html
- twitter #drupalusability tweets
- Mark Boulton upcoming activities http://buytaert.net/mark-boulton-to-help-with-drupal-7

Proposed solutions:
- remove of "Post by topic" and "Quick UX review please:" blocks from usability frontpage
- rewrite "We are working on:" block with quick blurb what the group is about + link to http://drupal.org/community-initiatives/drupal-core/usability + how to contribute (join, #drupal-usability irc, #drupalusability twitter tag etc).
- keep maintaining http://drupal.org/community-initiatives/drupal-core/usability page for latest action
