Considering how dominant it's been as one of the pillars of the social media era, it's funny to think about how young Twitter actually is, and TwiAge helps put that into perspective. The Twitter bot scans one's account and automatically determines how long they've had it for, showing the relative nascency of the platform in the process.
Twitter is barely more than a decade old, even though it seems to have dominated social discourse for a lifetime. This means that people's Twitter ages should be treated on an adjusted scale compared to human ages, in the same way that dog owners talk about dog years. A five year old Twitter account is akin to a thriving twentysomething, while anyone with an account over the age of ten is more like a nonagenarian.
