Basta is managing director of Magister Advisors, a boutique investment firm with offices in London and Silicon Valley. In a research note this week, the firm said that Twitter is a logical acquisition candidate for someone like Google (GOOG) or Facebook (I argued in an earlier post that Google’s de-emphasizing of its own social network, Google+, makes it even more likely that the company will eventually acquire Twitter, although others seem to disagree).

Twitter would be worth more to a larger business that can accelerate innovation at the company than it is as a public entity, says Basta. “Market expectation was that Twitter, having created a completely differentiated platform, would accelerate innovation and introduce products and features that would justify a $60+ share price,” he said. “Disappointingly, innovation for users has largely stagnated. Furthermore, user acquisition numbers have slowed and many sign up and don’t activate.”

The company has made progress in its efforts to monetize the platform, said Basta, thanks to acquisitions such as the mobile ad-network company MoPub. But the service still lacks features, and that is driving down the value of the platform compared to others such as Facebook (FB).

“Twitter still has an opportunity to be a successful standalone business, but to date it has squandered that opportunity. The business has made around fifty acquisitions since 2008 but the user experience has remained largely unchanged since launch,” Basta said. “The business is still essentially an overwhelming firehose of crowdsourced data. Without a better way of sifting data or sorting and compiling a user’s own posts the platform will almost certainly find that its user base begins to run out of steam.”
