Steve Matthews of Stem Legal pointed out that what I thought was a special integration is actually just using LinkedIn’s API. Steve doles out the details in a comment to Kevin O’Keefe’s post [If you can’t beat ’em, join them] and points to this post on the LinkedIn blog: Get Your Inside Connections with BusinessWeek & SimplyHired
Sure enough, I went over to SimplyHired and it has the same functionality as Martindale. In a job search site, the LinkedIn functionality is even more powerful than Martindale. I still give Martindale credit for moving in a better direction. But they lose points for originality.
