Very useful and free website where you can ask members for product or service recommendations. It's great because it's not a list of products with star or number ratings, it's a question/answer format. You can ask very detailed and specific questions and receive detailed answers/recommendations from others.
For example, you might be in the market for a new car, and you live in an area with heavy snow and a steep driveway. You could post a question for recommendations of cars/trucks that would do the best in snow and snow/ice covered inclines. Then other users of the website would post their own car recommendations along with why they would recommend said car. Or say you are very tall with long legs, like my father, and need a car with enough leg room in the driver's seat. You can ask for recommendations for such cars. You can have an in-depth, back & forth discussion with the other users to find out things that you might not read in general reviews.
If no one is able to offer you any suggestions after a day or two, then the Yabbly team will actually do some research and provide you suggestions
The team also puts heavy emphasis on their user's experience with their site. They really listen to users, take suggestions, many of which they have implemented, and fix glitches very quickly.
I think it's an awesome site, it just needs more users.
