What do the best corporate blogs do well? “Is corporate blogging dead?” I hope we all know the answer to that question. And yeah, I was having a little fun with the title. But, the fact remains that 28 percent of Fortune 500 companies have a public blog. Not a bad number. Especially considering we’re talking about the biggest of the big. What about the thousands of other blogs from midsized and small businesses out there? No doubt, those numbers are fairly large.
