Do you have Google Toolbar With Sidewiki installed?
If yes, please, watch the navigation bar of your browser.
I am using Firefox and noticed a hashtag after the URL in many instances. Not always, so I am not sure about a pattern, yet. When I turn Sidewiki off in the toolbar this effect disappears. Here is the proof.
Google Toolbar Seems To Interfere With Other Browser Add-ons
Shortly before the page finishes loading I see #atssh-linked appended to the url for the fraction of a second, then it changes to # and stays there. The great problem with this kind of URL manipulation is social bookmarking plugins, bookmarklets, and if you save a bookmark use this URL with the appended #.
This could dilutes some of your social bookmarking efforts since, index.html and index.html# are considered two different URLs by some social bookmarking sites like StumbleUpon for example. Digg and Reddit seem to handle it well though.
Am I dreaming or does someone else share a similar observation?

While this is used as an exploit right now, it reveals a major design flaw which unfortunately for the blocking script can be fixed rather easily. Besides that it's just a usability issue.
Google finally pays attention to those fragment identifiers within a page. And they can be quite useful for the user experience if used correctly, however, seems the Sidewiki development team didn't pay much attention. I imagine, it won't take long till it is fixed. Then the blocking script magically stops to work and all Sidewiki comment suddenly rise back into existence.
