Mashable's as put together a great top 10 list of things to do to help increase your personal brand in the workplace. One of my favorites:
"It’s really easy to brand yourself an innocent observer. The problem is that consumers aren’t sharing any value with the world, while producers are building value in themselves and getting their ideas noticed. Try and start a podcast series or write a blog about what you love. Something you’re really passionate about, whether it be work or play. People will begin to notice and be drawn to your brand. Being a producer is much more rewarding, and it causes your network to flourish, thus positioning your brand for career success."
