(CNN) -- Twitter is testing a major profile redesign that's very reminiscent of Facebook and Google+. Mashable assistant features editor Matt Petronzio spotted on Tuesday a huge update to his Twitter profile page, with the main picture and bio scaled to the left and significantly more real estate dedicated to the header photo. The revamped tweet stream is also a departure from its signature look. There is a greater focus on photos and content cards. It moves away from a strictly vertical timeline too.

Experiments typically go out to a small, random pool of users.

Although @placeholder isn't verified on the site, there's an option for the stream to show "Tweets" and "Tweets and replies" for every user â€” a feature typically reserved for those with the blue check mark.
