The optimism and excitement with which Paul Levinson writes about blogging is apparent. He makes the saying "you can make a difference," very believable. In the section "Changing the World with Your Blog," Levinson gives an example of how Joan Walsh, editor of the blog Open Salon and frequent guest on several MSNBC shows, and himself, to a lesser extent, influenced Barack Obama's decision not to delay the debate between himself and Senator John McCain in 2008. Walsh responded to Levinson's blog saying, "Paul Levinson speaks, Obama listens!" Although this may be an exaggeration, it highlights the potential that every blogger has to influence anyone even the President of the United States.
Earlier in the chapter, Levinson discusses several instances in which he received feedback from several actors or from family of the actors who read his blog. Rich Sommer, who plays Harry Crane in AMC's "Mad Men," not only corrected Levinson but expressed his gratitude for Levinson's reviews. A similar exchange took place with Idris Elba, who played Stringer Bell on HBO's "The Wire." Like Sommer, Elba also thanked Levinson and the two shared some musical interests. Levinson also heard from Len Cariou's ("Brotherhood") wife and Aaron Hart's ("Mad Men") father. This must be a rewarding experience for any blogger. Influencing the President and chatting with certain celebrities, which a few years ago was seemingly impossible, are just two prime examples that demonstrate the power of blogging.
