LetsLunch, a networking site that aims to help business professionals meet up for lunch, has just launched version 3.0 of its service, adding some additional features as well as expanding service to the U.K. The service works by allowing business professionals to sign up and create a profile that outlines their industry and interests, as well as when they might be available to have lunch with other users. Then the site matches you up with other business professionals in your area who might be relevant to your interests and you can choose a specific time and place to meet. When looking for users to lunch with, you can view short bios, a list of professional interests such as online media or entrepreneurship, and even reviews from other users who have lunched with them in the past. You can also see links to social networking sites like Twitter and LinkedIn if you wish to connect with them further. Version 3.0 gives users the option to become \u201csponsored lunchers,\u201d helping them to be seen by more users of the site and thus making the most of their networking opportunities. Other upgrades include social media integrations, group lunch features, and of course expansion into the U.K. market. The whole idea behind LetsLunch is to \u201cmake your lunch break count.\u201d Instead of just eating a sandwich at your desk or picking up fast food, you can actually make new contacts that might help further your business interests. Though there are plenty of sites that allow business users to meet others and talk online, this one actually facilitates face-to-face meetings, so there can be more chances for expanding your actual network. Many business owners and professionals may prefer a more traditional or organic form of networking, but many aspects of business are being changed by the Internet, so this type of site may not be such a huge leap. Especially for people who may have a hard time building their business network naturally, such as those who work remotely or have recently moved to a new city. \u00a0A service such as this could prove valuable in a number of different capacities.
