It's Special!
It doesn't play well with others? 
It's the first of more future tabs? 
All true!
The blue bar at the very top is for your own personal stuff. A clock (yay!), your profile, a logout button (I'll never use that, though), and the mail tab.
The grey bar contains the site-wide main feature points - database, ideas, lists, etc, plus the search.
The search will work depending on where you are. i.e., if you're in the plants database, the search will only search plants. Ditto ideas, forums, blogs, or mail.
In the footer contain all the miscallaneous links that are needed for the site (about us, links, newsletter, memberlist, etc).
That's the thought process behind where something goes.
