Twitter Co-Founder Doesn’t Care That Instagram Has More Users

This week Instagram passed Twitter for total number of active users, registering 300 million to Twitter’s 284 million.

As I wrote in my post, it’s a big deal inasmuch as the active user number is easily the most reported metric for all social platforms. Lots of people seem to really care about it. But here’s one person who doesn’t: Twitter co-founder Evan Williams.

In an interview with Fortune, Williams downplays the value of a monthly active user, even going so far to question what it actually is.
