If you are reading this blog and find that there are pop-up ads or framed ads around the edges or in a different format than you see if you were to use the blog's direct URL, then you might be viewing the blog through some cookie-directed third-party vendor (especially if you first accessed this blog via a third party not of the scope of a Google or a Twitter or a Yahoo. etc.).
If this happens to you at this blog (or, indeed, at other websites that you visit), you might want to try cleaning your collection of cookies and re-entering the site directly from the BrainBlog URL.
Hopefully, this hasn't happened. However, I have heard from some other bloggers that their readers have had recent problems of this type.
