Social network / recruiting service LinkedIn on Friday announced they've achieved a big milestone in surpassing 300 million members. Unsurprisingly, a large portion of the site's growth has come from mobile - a demographic that is expected to account for 50 percent of all global traffic later this year.

In a blog post on the matter, LinkedIn highlights the fact that members in dozens of regions including Costa Rica, Malaysia, Singapore, Sweden, United Arab Emirates and the United Kingdom already use the service more on their mobile devices than on their desktop computers.

On a daily basis, LinkedIn says they see an average of 15 million profile views, 1.45 million job views and 44,000 job applications across more than 200 countries through mobile.

More than half of the site's members are located outside of America. Within the US, roughly 100 million people use the site so it's still very popular stateside.

It's worth pointing out that LinkedIn's figures represent registered users, not monthly active users. That figure is actually much lower at only 187 million as of late last year and highlights the fact that LinkedIn is still having a tough time acquiring member traffic. After all, a lot of people only visit the site to update their resume or to search for a new job.

That's not to say that they aren't trying new things, however. The company has acquired a number of startups in recent memory including Bright, Pulse and SlideShare to bolster their overall offering.
