The product recommendation service Goodrec, launched at 2008, left beta Monday night, and opening to all. It's the Twitter of user reviews--it limits commentary to a simple thumbs-up, "mixed bag," or thumbs-down rating, plus 160 characters of review text. The iPhone app for the service is location-aware, helping you find restaurants or bars near where you are. Unlike on the obvious competitor Yelp, you can write reviews from the mobile app.
I like this service. It's easy to use and there's a lot to be said for the enforced brevity of the content. It reduces rambling. On the other hand, you'll never get the depth of detail you get in a good Yelp review.
Goodrec covers restaurants and bars, as well as wine, movies and books, local attractions, and consumer products. It also pulls in headlines and links from reviews on CitySearch; other sources are likely to follow.
You can also set up little social circles in Goodrec, and read reviews just from your friends. Once enough people get on the system, that could be very useful
A specialized subset of Goodrec, "GoodFood," is pending approval in the app store, CEO Mihir Shah told me.
My Goodrec review of Goodrec: Good review app. Useful in spite of brief reviews. Great match for iPhone. Definitely worth a shot.
