Fixed UL/OL indentation and style-type
h element skip - correction

You can'y just jump from h1 to h3. What about h2?
The W3C specification is very clear about this: one h1 in a page, and then you use unlimited h, but you must keep the order - you can't jump from h1 to h3 exactly like you can't junp from h3 to h2.
Fixed word wrap in "last comments"
Fixed .question-summary-wrapper (caused problems)

"Unfloat" .question-summary-wrapper - it's needless and break the line when the title is long. See <a href="http://img442.imageshack.us/img442/6770/buget.png">image</a>: <br /><img src="http://img442.imageshack.us/img442/6770/buget.png" alt="Float bug demonstration" />
