Twitter seems to be always experimenting as to how the social network works. The latest move from Twitter is to replace the favourite star with a heart, but only on the Android app for now. The heart symbol is currently being testing in two different designs: circle hearts or borderless hearts. For now, only a certain number of users will be seeing the change.

Only recently, previous investor in Twitter released a memo called “What Twitter Can be” in it he mentioned that the social network “Bring on the hearts.”

“If Twitter integrated a simple heart gesture into each Tweet, engagement across the entire service would explode, more of use would be getting loving feedback on out posts and that would directly encourage more posting and more frequent visits to Twitter.”
