Google Adwords don't work
If I create an ad on Google Adwords that points to one of my articles using the simple URL, Google will encode the URL so that the clicker has to click it in order to see the actual URL (I assume this ensures they get the money from the click by not allowing the user to see and type the link themselves right away). Anyway, when the user clicks said advertisement, Google inserts a clickid (gclid) into the URL that breaks the simple URL, because it doesn't realize it's a query string and attempts to start a new one. The result is an ad that points to an article with no text in the page.
Fixed for the next build. VaultWiki will ignore any part of the title string that starts "?gclid=". If there are other situations like this, please post them so I can develop customizable tool.
