I hadn't expressed my personal opinions regarding this specific matter before this page, and as I am a different voice from those before, adding my two cents to it - that is, if this system is to stick around rather than be purged, as I'd admittedly definitely like it to be, an easily locatable and very apparent feature that lets users to opt out from the statistics being reflected on their very own profiles is an absolute must and the bare minimum to be done as soon as possible, and by all means [i]should[/i] have been completed before anything like that was implemented in the first place - is a perfectly valid course of action. 

At the very least, the more people speak up, the easier it is to gauge what the general opinion of the public is, so to speak. (Alas, and the general public is often too apathetic or too afraid of the authorities to speak up when they don't like something.) We don't just want real problems to be swept under the rug, either. Thus far, at least one person has stated to me that this one thing is effectually something that means they'd be quitting the site. (As far as I can see, hasn't spoken up on this thread.)

As for "go to last post" issues, then wouldn't it be more of a topic for bug/help forums? Not really a feature in development (aside of debugging being a part of development process, anyway)...
