No, you're not going crazy—Twitter has a new font, and it's called Chirp. In addition to the font facelift, Twitter made a few other changes to its interface as well.
Your Tweets Will Now Be Written in Chirp
Twitter's new design brings a series of small, yet very noticeable changes. In a Tweet, Twitter's design team announced that the makeover will make the site "more accessible, unique, and focused on you and what you're talking about."
The new font, Chirp, is the most prominent of those changes—but it's also the most divisive. You'll find the font all over the desktop and mobile versions of Twitter, from the headlines to the text that makes up Tweets.
Twitter says that the font makes any text written in a Western language align neatly on the left side of the screen, giving users a more pleasant experience when reading and scrolling. The font for non-Western languages will remain unchanged, however.
Chirp is definitely different from the platform's previous, non-propietary typeface, so it's going to take some time for the Twitterverse to adapt.
But That's Not All ...
Besides the font, Twitter made some other site-wide changes to its visuals. The platform turned up the contrast on its colors, and also made them significantly less blue. According to Twitter, this will make videos, pictures, and icons stand out more on your feed.
You might also notice that some of Twitter's buttons look a bit different as well. The Follow button, for example, is now black with white text, instead of white with blue text.
Twitter did away with some of its gray backgrounds and divider lines, and also added some extra space in your feed. It's all an effort to make Twitter easier on the eyes, and an overall better place for its users.
What's Next for Twitter?
This likely won't be the last of Twitter's design changes. Twitter said that "this is only the start of more visual design updates as Twitter becomes more centered on what you have to say."
But not only has Twitter been busy with design changes, it's also been working on a slew of new features, like the Super Follow and a Shop module.
That said, it's no coincidence that the site's redesign precedes the debut of Twitter's upcoming features. The redesign was likely made to accommodate these features and make them more noticeable.
