In my hunt for the new Amazon product wiki I found 3 new features I didn't know about.
First, I found this on Harry Potter Book 5. It lists the books that cite the title you're looking at … pretty nifty … and potentially handy if you're looking at a scholarly title.
Tags??? Tags are everywhere now. This I found on every title I looked at (see the Harry Potter example) … no explanation needed.
The last new thing I found was Customer Discussions/Forums. This one was on one of the bestsellers I clicked on to find the wiki – The Lighthouse. It looks like the precusor to the wiki …
It looks like everyone is jumping on the communication & collaboration bandwagon, it's all pretty neat, but it makes for very cluttered product pages … I'm interested to see how all of these additions are organized in the future.
