Well... I'd argue that quantity does not equal quality - is the startling difference between right-leaning and left-leaning posts reflected in the titles, or does the use of inflammatory rhetoric in topic titles reflect an anti-[position] bias? As an example: The thread entitled "Obamacare is still unconstitutional" is clearly an anti-Obama position, but reflects in the search results as an appearance of the search string "Obama." On a similar note, if a topic existed about "Bush-league baseball" - that would also show up in a "Bush" search.
Results are not always what they appear.
