The other issue that you're going to have with TWTR as of today is that Facebook just released their earnings and they beat expectations, which ultimately means this: Facebook is making money. So now Facebook represents the flight-to-quality in the social media space, which leaves TWTR looking like a complete train wreck, which it is. Look, Twitter is no spring chicken. They've been around since 2006, which means they've had a complete decade to figure out how to monetize their service. If they haven't figured it out by now, it's likely not going to happen. The most they can hope for is a fire-sale buyout like the one YHOO just went through, based strictly on the fact that they have a lot of users. But who couldn't get a lot of users offering something for free that's ultimately a huge money loser?
When it comes to mass market social networks, teens are using Snapchat and Instagram, and adults are using Facebook for personal and Linkedin for professional. Some say TWTR is more suited for "real time news" but I just don't think this world was ever lacking in news sources to begin with, especially considering that TWTR doesn't actually create any news, but instead is just a middle man between the consumer and the actual news source. It's actually a really shitty position to be in.
