I hate to talk about reddit, but...
I was there for a dozen years or more, posting and commenting several times most days. In other words, I was active.
Part of that meant going to the website regularly, and I developed a muscle memory for "r e d <tab>" which could be typed with three fingers on one hand.
I catch myself even a year after leaving. It was an EXCELLENT name in that regard. My Mastodon server requires two hands and at least four fingers ( m s t <tab> ).
