I was up at the Topsfield Fairgrounds yesterday with my Nikon D80 testing out some features. These photos are over on flickr and also at Tabblo.
One thing I don't like about Tabblo is that even though it has links to flickr, they are only one way. Tabblo can ingest the flickr photos to make a Tabblo, but once you make the Tabblo, viewers can't link back to flickr to leave comments.
