By Bill Kennedy - Chris Brogan, a social media expert, just tweeted about a great concept called the Brag Bag. Every Friday Becky McCray, who runs SmallBizSurvival blog, posts an article encouraging people to add a comment about something they're proud of. Some people talk about personal accomplishments. Some people brag about what friends or co-workers have done. Others just leave a high-5 to the other people who left their comments. The result is an energetic, positive tribute to the human spirit.
