As one of the people who decides where and how brand marketing budgets are spent - I would say Twitter's advertising product and approach is far more viable and attractive than Facebook's is (or ever has been). On top of that, the work Twitter is doing with TV networks, producers, and sporting organisations is unique and has a high chance of success because it provides value to those organisations. While some have tried, nobody else has come as close as Twitter to accessing and disrupting the $180B (annual) TV advertising market. I wish them luck. I think they're going to nail it.
