I'm approaching my one year anniversary on Twitter ( @wikimurph ). My first tweet? "Mountain biking in OC." For some reason I felt the world needed to know that. One year and hundreds of tweets later I've learned the true value of Twitter. Twitter is a real time wiki. Although Google won't admit it, Twitter is a search engine, not a "poor man's email" as it was recently derided by Eric Schmidt. Twitter allows us to tap into the brainpower of people around the world, trusted advisers and total strangers alike. Over time I noticed that I've gravitated toward people who write tweets that share knowledge ("just saw a presentation about...), tweets that pass along a provocative observation ("has anyone noticed that..."), tweets that point me toward content I might not otherwise have stumbled upon ("check out this site..."). I am following brand strategists, marketing gurus, social media wonks, designers, pop-culturists
