I'm also getting the following category but just for blogoscoped.com ('cause the site is in Google News):
It just links to a Google News search...
Wow! I already got 70 subscribers with Google services alone over at SEO 2.0 after 7 weeks of hiding my "subscribe" link at the far right bottom...
Tadeusz: The subscribe button is right there in the address bar, as soon as you add proper LINK tags in HTML, which you did.
Philipp > it works only for the English version of Google News :-/
Microsoft is also going to have it's own Webmaster tools control panel:
Send a mail to lswmpmicrosoft.com to apply.
The feature is not as useful as it seems. Google already bought FeedBurner--why not enhance those statistics if the site is already enrolled in FeedBurner?
I get 12 subscribers in GWT and these are the subscribers to the original on-site feed which I have since permanently redirected to FeedBurner. FeedBurner shows 35 subscribers from Google-related readers (Google Reader, iGoogle).
This also shows that Google Reader does not follow the permanent redirect (HTTP 301) by updating the URL in its database. This may be a bug (or a feature).
GReader does follow 301 redirects as far as I am aware. This actual discrepancy is caused because the Webmaster tools is showing the number of people subscribed to feeds hosted on your website, FeedBurner is external though so is not included.
This will probably be fixed as FeedBurner becomes Googlified.
And here's the official post on the Webmaster Central Blog:
