Twitter is testing a new design that focuses heavily on photos and content. With a large profile image the “new design” is certainly reminiscent of Facebook and Google Plus profile pages.

It is widely known that in the past Twitter has contemplated abandoning its traditional timeline and text heavy design in favour of a more visually appealing content rich layout.
10 years from its initial release, Facebook is still the largest and most popular social platform, therefore a new Twitter design that is similar to Facebook’s would not be surprising -as the old saying goes if you can’t beat them join them!
Twitter often tests new design updates before rolling the changes out to the general public, so don’t be surprised when your twitter profile changes in the near future!
