Cellartracker is a SAAS application that enables an individual to maintain a wine cellar on-line. This is not a new idea – you can find half a dozen such applications on google.com. What makes Cellartracker unique is the fact that in addition to being a hosted application, it has an open source wine database. So, when you go on-line to add a wine, it automatically searches to see if any other user has already added that wine. If so, you can use the existing item record, including reviews, scanned labels, and any other information that the other person might have entered. In addition you can read reviews and notes (e.g. when to open the bottle) that other users have posted. Check it out at http://www.cellartracker.com
I think Cellartracker is a great example of the direction that consumer applications are beginning to take – hosted, open source/community based, and free!
