Flipboard has become a massively popular service in the past few years. On Wednesday, the company announced that it has 50 million readers, more than double the amount than in August, when it reported a 20 million reader figure. In addition, it is also launching a new feature that allows anyone to curate and create their own in-app magazine, with major publishers already using the service. As an added bonus, version 2.0 of Flipboard now allows readers to also search based on hashtags and topics. Flipboard calls the release its “most ambitious undertaking” to date. We spoke with Flipboard’s CTO Eric Feng (formerly the CTO of Hulu and a partner at venture capital firm Kleiner Perkins Caufield & Byers) who told TNW that while the service has typically been about feeds that Flipboard has created, it is moving in a direction whereby users can now create their own feed centered around topics, events, or simply personal interests.
