Twitter will have stickers soon, just like Snapchat, so that you can add cute little symbolic expressions of your feelings to your photos. The stickers will be searchable, like a "visual spin on the hashtag," Twitter explained in its announcement.
The stickers, Twitter's announcement emphasizes, are primarily supposed to be fun - the sample illustration shows one user adding some cool sunglasses to an elephant.
In the grand tradition of social networks gobbling up features that are already available on other, competing platforms, Twitter's stickers are a lot like Snapchat's stickers (except Snapchat's stickers aren't searchable).
Although it appears that the stickers will only be usable on mobile when they roll out over the coming weeks, anyone - even the weirdos among us who primarily use twitter.com to read Twitter - will be able to click on a sticker in a photo to pull up a feed of how it's being used across the network. Users can add an unlimited amount of stickers to each photo, each uniquely searchable.
Twitter will rotate the available stickers regularly, although it doesn't say how often. The library, the company said, will contain "hundreds" of choices at any given time.
