For those of you missed it because you were too busy getting on with your busy recruitment lives (yes, that’s all of us), LinkedIn announced its latest quarterly earnings last night. Unless you have purchased their stock, you won’t care too much but LinkedIn also announced some updated visitor stats that are interesting: As of the end of Q3 2011, i.e. the end of September, there are 131.2 million members. That’s a whopping increase of 63% from the Q3 growth last year.
