Now, for the good news There are several positives that were somewhat lost in LinkedIn's gloomy EPS and EBITDA guidance. For example, the $2.9 billion in revenues expected in 2015 is a more than 30% improvement over the prior year's $2.2 billion. Also, despite its niche market catering to professionals and job seekers, LinkedIn continues to grow its membership base at an impressive clip. Last quarter, LinkedIn added 17 million new members, pushing its total to 364 million. By contrast, Twitter which plays in a much bigger potential user market than LinkedIn added just 14 million monthly average users (MAUs), bringing its total to 302 million. And with over 50,000 posts each week, LinkedIn's users are actively engaged and becoming more so daily while Twitter continues to have more visitors monthly that don't become active users than actual MAUs. The first quarter also saw a milestone of sorts: for the first time ever, over 50% of the unique members that logged into LinkedIn in Q1 were of the mobile variety.
