We’ve moving into summer but the pace of activity doesn’t seem to be slowing for the online recruiting and job board world. I hope to see some of you at this week’s JobG8 Job Board Summit in Chicago – but in the meantime, here’s all the news that’s worth reading:

• LinkedIn beats revenue numbers – but stock still falls: Although LinkedIn managed to beat revenue and profit estimates for Q1 2013, Wall Street didn’t like the guidance for Q2. Well, we know that the stock market is a fickle lover.
• Niche job boards tops for effectiveness: A U.K. survey by jobs.ac.uk indicates that 71% of respondents prefer specialist job boards to generalist job boards. Not surprisingly, lack of skilled candidates continues to be the biggest challenge for employers.
• Twitter cards for social recruitment: Work4 has integrated Twitter Cards into its social recruiting platform.Twitter Cards, which are offered only to Twitter-approved developers, are small attachments that are added to the bottom of a tweet. When a user clicks on the card, it expands and shows additional rich media, such as summary text, photo, or video. The Tweets just keep getting longer.
• Is CareerBuilder too valuable?: While the parties involved aren’t commenting, Crain’s Chicago Business and The Wall Street Journal are both hearing from sources that sale of Tribune Company is hitting a snag because of Tribune’s part ownership of and Classified Ventures. While The Wall Street Journal suggested that Tribune group as an entire package could bring a price of up to $1 billion, it also priced CB and CV together at $700 million.
• eQuest gets some big numbers: eQuest that its collection of job board and social media candidate performance statistics has reached 1.25 billion.  eQuest collects and stores these statistics as part of its Big Data Recruitment Suite. I guess this is the ‘big’ in Big Data.
• Smart move: Treehouse has launched a job board that aims to bring new opportunities and income to its student body of 35,000 coders of all kinds. The jobs come from companies around the globe and include development and design positions, including mobile developers and junior-level developer. Teach ‘em and hire ‘em.
• eHarmony moving into the job board and/or matching world: The pioneering online dating site eHarmony has announced plans to launch a job site in 2014 that focuses on the ‘fit’ between companies and candidates, based on detailed information about both. This assumes, of course, that people are as honest about work as they are about dating.

That’s it for now. More news next month!
