You're no longer subscribed :)
I am very sorry about this. I have been fooling with solutions that would allow people to be notified when a particular page was updated, or content in a particular category, and it's been a road filled with potholes.
The latest pothole was a bug in the notification plugin i was using that should/would have been caught had the developer done even rudimentary testing. As a result, i lost all subscriber info and wasn't able to restore it, thus i removed the plugin and, in so doing, the option for readers to be notified of page updates. This will effect followers of my Firefox stuff mostly.
The only solutions that remain to be notified of content updates, for the time being anyway, are listed in the Subscribe page.
