I did not know that Twitter changed it's main page interface until I logged in to my account a while ago to participate in the Follow Friday love.

As for me, I like Twitter's new look. It's refreshing and cool. The blue all over the page added those factors. I also particularly noticed the POPULAR TOPICS BY THE MINUTE, DAY, AND WEEK section. In that case, I will know what are the trending topics at Twitter even if I am not logged in yet, cool. The search box also is pretty much helpful. And oh, really cute frontpage bird by the way!

If you did not see Twitter's new face yet, better see it today.

P.S.
I was so excited to log in but was slightly disappointed after doing so because I see no changes in the inner pages. Oh well.
