Anecdotally, the process to get to Facebook for many members of my family is to Google "f" or "facebook". They know how to go directly there but for whatever reason prefer Googling it. I have heard the same from friends about their (typically older) family too.

At this point I would assume most people who use Facebook routinely type 'f' in the address/search bar and it autocompletes immediately to the full Facebook URL and they just hit enter. Trying to get Chrome to search for facebook instead of going to facebook.com takes extra effort.

I add reddit to search terms when I want to search reddit for a topic.

Yeah, the only way to search reddit and actually get what you are looking for is through Google. I don't understand why the website's search is so bad.

Probably because everyone just uses Google anyway.

And good search is hard to do.
