Riffs is a newcomer to the world of consumer review sites. This category to date has been dominated by epinions and Planet Feedback. Riffs - which was developed by a startup called attap - is trying to break in with some neat Web 2.0 features.
For example, Riffs has Blikis - a combination of blogs and wikis. Using Riffs the community can decide on the content for any given item being reviewed, how riffs should be organized and more. Each user also gets their own page, where he/she can organize their riffs and record your commentary about anything. They also offer RiffRolls that bloggers can incorporate into their own blogs as well as a nice set of mobile features.
Take a look at this in action. It's pretty cool. Here's a review of the iPod nano. It includes the usual thumbs up/thumbs down reviews plus user comments. But look closer and you will notice that this product has its own wiki history, user tags and an RSS changes feed. Outstanding! Great work gang. (Hat tip: 37 Signals)
