Back in the “a few months ago” days of Tumblr, there used to be red numbers instead of pretentious blood orange numbers in the inbox new message notifications. People would put a 1 or infinity sign or 0, depending on how they would act. The 1 represents “please send an ask to me, I’m an ask blog so I’ll answer your question!”. The infinity means “lol send as many questions as you can!” and the 0 means “why isn’t anyone sending questions..?”
