As I was browsing Twitter.com this morning, I refreshed the page, and something jumped out at me: the font was different.
The change was minor — Twitter hadn’t suddenly switched to a serif font or anything like that. But a quick Twitter search showed that I wasn’t the only one who noticed the shift, and my co-workers did, too.
It’s unclear why Twitter changed the font, and the company didn’t immediately reply to a request for comment. (It has dissolved its press office, so I’m not expecting one.) And the company hasn’t posted anything on @TwitterSupport, where it’s shared a lot of recent product updates.
For me, I’m only seeing the font on the web and mobile web; on the iOS app, I still have the older font. I’m guessing the new font will make its way to other platforms eventually, so if you’re not seeing it yet, consider this your warning.
