Did you actually read the tweet that you replied to?

> "I'm certain I scroll at least 100 tweets/minute."

Many Twitter users, including literally the person you are in conversation with, scroll through dozens/hundreds of tweets a minute.

Not sure if you're actually used Twitter before, but many tweets are only a line or two of text, and it doesn't take more than a second to process them.

Additionally, if you're quickly scrolling through replies or someone's history to try to find something, it can render hundreds of tweets in a matter of seconds.
