The company is beginning to tailor suggestions for new users -- according to their past web browsing history, as well as whom other Twitter users follow.
The project is still in an experimental phase and only being tested in some countries, but all indications are that it points to a more permanent shift.
Before, new users would be presented with nearly identical suggestions for users to follow when they got started.
"Since you have individual interests, you should get individual suggestions," Othman Laraki, Twitter's director of growth and international, wrote in a blog post Thursday. "After all, even though millions of people love Justin Bieber, FC Barcelona or Kim Kardashian, not everyone using Twitter may want to follow them."
Like many social networks, Twitter gets visitor information from websites that have integrated Twitter buttons or widgets, so it knows which users have been on those sites.
"By recognizing which accounts are frequently followed by people who visit popular sites, we can recommend those accounts to others who have visited those sites within the last ten days," Laraki writes.
So it appears no coincidence that Twitter announced earlier Thursday that it had added a "Do Not Track" feature for users to opt out of the network keeping tabs on other sites they visit. "Do Not Track" is a cookie-blocking option in the Firefox browser that the Federal Trade Commission has been promoting.
Now, when new users sign up for Twitter, they will be given an option to "Tailor Twitter based on my recent website visits," according to the blog post. They'll also be able to follow a link to learn more about what that means.
Current users will also have a new "Personalization" option in their account settings, to make follow suggestions more tailored for them as well.
A Twitter spokesperson declined to specify the countries the new tailoring features is being tested in, beyond saying that European users are not yet included.
