I'm one of the folks that don't like the left nav bar (hanging out mostly on EESE). I tried hiding it, but notice that I constantly need to hit the "Questions" choice.
If I just click on the site name, I get sent to a home page, with a limited "Top Questions" list. I suggest that this page has very little, if anything, that's not on the "Questions" page, and is simply fairly useless. I don't see anything on the Electrical Engineering Home Page that's of help to any user, old or new, that's not on the Questions page in a more useful form.
Why not get rid of the Home Page? That way, I have a Questions button (the main site link) and I can hide the silly Left Nav bar with impunity.
