I quite like the "flair" concept. There is a feature called "web slices" in Internet Explorer 8 (and Firefox with the right add-on) that allows you to have buttons on your bookmark toolbar that, when pressed, show just a relevant part of some web site. The idea is that you can use that for stock quotes, the weather - or, now, your StackOverflow flair.
Sadly, the way web slices work means that it is the owner of the web site who must add a little bit of markup on the page to enable IE's "make a web slice" button. So let's do it!
Web slices are described there. Basically, the
<div> you want to make into the webslice needs to be of class "hslice", with an
id attribute, and that
<div> must contain a
<p class="entry-title">. The entry title is the default name for the web slice on the toolbar, and whatever's in the div gets displayed when the user clicks it. There are other attributes we can use to allow IE to periodically check for changes and tell it how often to check.
The many Firefox users can also use web slices if they install the "webchunks" add-on. It's at https://addons.mozilla.org/en-US/firefox/addon/8494
