Just observed this today.
The page title is being changed to Tuts+ (sairam) on Twitter instead of Tuts+(tutsplus) on Twitter . This was not the case earlier . See a sample twitter screenshot . The source html is normal, looks like the title changes after the page load is completed.
<title id=”page_title”>Tuts+ (tutsplus) on Twitter</title>
My username is being shown on the title of the screen when viewing other twitter profiles which really annoying and is degrading the user experience. I have tested this on Firefox and Safari. This shows up only when a user is logged in. Screenshots attached.
