If Twitter was worth paying for, they wouldn't have used an ad-supported model to begin with (because people would have found it valuable enough to pay for in the first place). In some ways, Twitter has the "news" problem in that people just aren't willing to pay for it. As this says, Internet advertising really isn't that effective, especially on a site that is the equivalent of standing in town square with a megaphone. I think Twitter is tapped out on how much money it can make and drastic changes will just drive users to other places. If you're looking for higher returns a different company might be a better idea.
