Mouthshut has been one of the big players on the internet when it comes to user-generated content. The first focus of the site has been to generate buyer review and feedback and it has done reasonably well until now. For each web entity to last this long, a certain money source is essential.

Epinions, the grand pa of review sites, went social and could provide an amazing opportunity for niche marketers to build authority and gain closely-targeted visitors. Epinions now has social networking profiles and offers the ability to put up a web of trust (i.e. Pals) with other reviewers in your niche. I am not recommending doing affiliate promotion and dropping links on Epinions at all! (Associate links are taboo).

Wish to compare prices? Need to buy something? Looking out for a gift? Wish to make an educated call before purchasing? Then, have a look at epinions.com. They supply buyers with totally free reviews on tons of products so they can pick which product they should buy.

Chris Whitten, Founder and Director of WikiAnswers remarked, "On other Q and A sites, similar questions get asked repeatedly again, and the answers cannot be improved on when they contain mistakes. On WikiAnswers we merge copy questions together and then grow them with collusion, so that good answers become great answers over time."
