Twitter has started testing a big redesign of its Web page, with larger photos reminiscent of Facebook and Google+. And apparently, I’m one of the lab rats.

I noticed an update on my Twitter “Me” profile page Tuesday morning. I wasn’t expecting to be part of what Mashable reported was a small, random pool of users in a test group.

And it was a little unsettling until I realized the similarities to Facebook’s already familiar Timeline layout, with an enlarged cover photo across the entire top of the page and the profile picture moved to the left.

But right below the cover photo is a feature that could be really useful – clickable stats for number of tweets, photos and videos, lists, followers and accounts followed. The landing page shows your tweet stream, but gives them a bigger portion of your screen than before.

Clicking on each stat changes the layout below. For example, clicking “Following” or “Followers” produces groups of Pinterest-style tiles for profiles, arranged in rows three across, for each follower. Each tile has smaller versions of your main profile page, with their cover and profile photos, and clicking the tile jumps right to their profile pages and tweet streams.

Similarly, clicking on “Photos/Videos” produces tiles for each photo you’ve tweeted, and the same goes for “Favorites.”

Sorting through the sections is all done on one page without having to switch pages as before. Your profile information and trending topics stay on the left side of the page.

It’s not clear whether this is a final design, but it’s all part of an already announced makeover Twitter is doing to unify its look across all platforms, from mobile to desktop.

Moreover, Twitter executives have said the biggest problem they’re trying to solve is to make the micro-blogging service easier to use and to understand for both existing and new users. Analysts are concerned about Twitter’s slowing rate of growth.
