The Mac Observer has just put up a review of Bookpedia. It's a favorable one. A few of the commenters have expressed curiosity about how how it compares to Delicious Library's feature set. Maybe some Pedia users who have prior experience with DL would want to contribute to the discussion over there. Seems like an opportunity for some civil discussion, or maybe I'm being optimistic http://www.macobserver.com/review/2007/02/01.1.shtml
I posted a reply there that referenced a TMO review
of Delicious Library. On that earlier review, I posted a series of comments, including a direct comparison between DL and DVDpedia (the one I use the most). Both Conor and Will Shipley, head of the DL team, got into the discussion. Shipley called me a "hater," but didn't respond to my detailed comparison, for whatever reason (perhaps because it was all true). I gave DL its due for having (at that time) better iSight scanning, the "similar items" tab, and others, but found serious limitations vs DVDpedia, especially exporting files and smart collections.
