Small Businesses Don't See Need for Social Media

It seems many businesses these days are on Twitter and Facebook in an effort to reach out to new customers and keep existing ones happy and informed. However, most small businesses, according to one study, don't seem to care about social media and don't consider it a must-have for the health of their businesses.

Hiscox, a small business insurance provider, polled 304 small businesses owners whose businesses consist of less than 250 employees. Only 12% of respondents said social media was a "must" for their business and about half said they couldn't do without word-of-mouth advertising. Additionally, according to a similar study by eMarketer, 64% of those polled said social media wasn't necessary or not something they had an opinion about.

These numbers throw a wet blanket on the idea that every business is hopping on social media to gather feedback and to please their customer base. Apparently, social networking is something looked to as a nice to have, but not a need to have for most small businesses.

Recruiters Troll Facebook for Prospective Employees

LinkedIn is a social network aimed at professionals and the working world, making it possible to keep in touch with current and former co-workers and being a great resource in finding new jobs. However, according to the Wall Street Journal, there may be a turning tide as recruiters and companies are now tapping into Facebook as a resource for finding new candidates.

For example, Waste Management, Inc. has more traffic to its careers website from Facebook than LinkedIn, showing that Facebook is home to more sharing than LinkedIn. The company's employees are joining groups and seeking out candidates by joining discussion. Other companies have launched specific recruiting applications in Facebook to gather resumes for specific job openings.

However, the situation isn't always rosy. Adobe reports that, in its experience, candidates aren't responding well when being approached via Facebook as the request is seen as an invasion of privacy. How would you feel about being recruited on Facebook?

Groupon Hits 115 Million Users

Groupon has grown immensely in popularity and has recently hit 115 million subscribers on its daily email offerings that go out to users. For perspective, at the end of 2010, the service had about 50 million users and, at the end of the most recent Q1, 83.1 million users were registered. This means that since March 31, subscribers are up 38%, signalling a huge growth pattern.

Even with competition from the likes of Google and Facebook, Groupon is still showing significant growth. This will be important as the company filed for IPO in June in an effort to raise $750 million. It should be pointed out that the growth has been through viral popularity of the service rather than acquisition of new companies.

Do you look into daily deals?  if so, are you a happy Groupon user or is this daily deals movement just a fad?

Gastrodamus Tracks Food Trucks via Mobile Phone

Food trucks have gained an amazing amount of popularity, especially on the west coast of the United States. These rolling cuisine serving trucks serve amazing food at great prices and have used social media to build a great following. In fact, a new mobile app will make it possible for you to track local trucks' Twitter feeds so you can see where the trucks currently are and specials for that particular day.

Gastrodamus is available for iPhone and Android devices and the mobile app is a project developed by a creative agency as a side project. The group is requesting feedback behind the app and is accepting suggestions on adding new trucks to the mobile app. Food trucks and mobile apps seem to go hand-in-hand, as trucks change their location every day and having a mobile app tied to their Twitter feed will allow mobile-based fans to get the latest info.

Are you a food truck fan? Would a mobile app make sense for you to stay up to date on your favorite truck?
