Yeah no worries. It happens a bit especially with paginated articles. I prefer to read mine as one page so I usually end up posting that link. I don't know if there is a way to include those types of ?parameters in the duplicate post search.
mk would probably need to implement URL normalization and comparison. As you say if you compare the 2 urls we submitted they only differ by the querystring parameters:

Actually I'm pretty sure the Framework has way of comparing URI's which would work better than this. int endIndex = url.IndexOf("?");
if(url.indexOf("#") > -1 && url.IndexOf("#") < endIndex) // catch those inpage bookmarks.
endIndex = url.IndexOf("#");
string urlToCompare = url.SubString(0,endIndex).ToLower(); //search db for this
You need to wrap the username in @ symbols to complete the shoutout. :)
