A big milestone for Twitter, but perhaps not as impressive as it initially seems
There are skeptics who challenge these figures. Twopcharts has noticed fluctuations with the Twitter accounts it has been checking while keeping track of the countdown to 500 million. In a blog post, the company states that out of 100,000 accounts it has looked at, many have been suspended or closed. Others are inactive, still showing the default egg profile picture. It's disheartening to some that 53% of the sample the company is analyzing is inactive.
