Twitter has been making improvements on its platform. Last week, the micro blogging platform changed its standard font to the Chirp font. Twitter detailed the Chirp font as one part of a broader brand refresh unveiled in January. "Notice anything different? Today, we released a few changes to the way Twitter looks on the web and on your phone.," Twitter said. Last month, Twitter was testing a new feature where users will be able to upvote and downvote replies on tweets, saying this is still not a 'dislike' button.
