The sometimes transitory nature of technology is aptly demonstrated by the recent decision by Google to shortly discontinue the availability of Google Reader. If you use Google Reader (or any other RSS reader for that matter) to read Grape Observer, and it interests you, could I kindly recommend that you also subscribe to receive Grape Observer by email to ensure that you continue to receive updates. There is an icon on the right of screen to do that.
As well as keeping the connection, subscribing by email builds a direct relationship with your author (i.e. me), something that RSS technology does not (I have little visibility over who subscribes to RSS feeds). And communicating with fellow wine enthusiasts at an individual level is something that I care about at the end of the day; frankly, it's the reason I write Grape Observer.
Thank you for your interest.
