LinkedIN: 100m Users

While 100 million users is an impressive milestone for LinkedIn, though its active users are below this number. As it prepares for a public offering, growth in users will be important.

"For LinkedIn, 100 million users comes with a caveat. As the company wrote in its S-1 filing, 'The number of our registered members is higher than the number of actual members, and a substantial majority of our page views are generated by a minority of our members' ...It’s important to note that 100 million is one-sixth of Facebook’s 600 million userbase. But as the company prepares for a public offering, growth in terms of users will be an important selling point for potential investors. And LinkedIn’s revenue and profit is increasing steadily."
