I don't know about msla, but i have my Gopher client right next to my Web browser[1] (yes the workspace is called Web, but they are both in the sort of same category of applications so i have them together :-P) and i use it quite often.

I mainly read "phlogs" though, but there is generally a lot of stuff to read when bored.

Are you asking how relevant the protocol was in the day to day back when it was popular? Or now?

Obviously, not many people still use the protocol, it has been almost entirely replaced by http. However, I used it a ton back in the early 90s. It was way more useful than the early web.
