If you're a curious person like me, you like voicing your opinion, finding new movies, reading useful articles, and sharing the best of what you find. There are a lot of social media websites that have these capabilities, but today there is a new entrant to the social media discovery arena: Lunch.

And for Mashable (Mashable reviews) readers, we have invite codes for previewing the site two weeks before it comes out of private beta.

Lunch: An Overview

Lunch's premise is simple: it is a platform and online community for discovering and sharing opinions and ideas. First, the platform: the company claims that its secret sauce is its Similarity Network engine, which calculates commonalities in tastes and opinions between people. Each rating, review, or game played helps the engine determine your tastes. This helps hook up members with reviews and information on specific charities, products, or ideas that they didn't even know they were fans of, but that the system calculated.

The second part of Lunch is its community, specifically the reviews: everything under the sun can be reviewed, from a political position to this Mashable article. Reviews can include images and detailed formatting. Users can rate and comment those reviews or have discussions. Lunch's goal is to replace reading hundreds of reviews and websites on products or ideas, but instead focus on relevant reviews from people with similar interests or mindsets.

The website itself is fun and fully functional. It offers a game called ExhilaRATE where users can compare likes and dislikes against the community, a full array of social networking features, and a bookmarklet, which makes it incredibly easy to review any page or idea. In addition, Lunch's founder, J.R. Johnson, has had success in the past, most recently selling VirtualTourist to Expedia.
