I like to stay relevant regarding product management. Any product manager worth his weight in salt has to understand the changes taking place in his environment. The easiest way for you to do so is through Twitter. I love Twitter. I know exactly what's going on in the news, celebrity gossip, tech and product manager in 140 characters and its awesome. In order for you to be up to date with the product management community I've compiled a list of product managers I think you must follow.
