Ha! Fair enough. No, I didn't intend to troll. I've found RCS useful for ad hoc versioning of configuration files on systems without git or other version control systems. Wondering whether anyone still finds it useful. I reckon not!
I've recently installed RCS on a Windows host for versioning my .emacs file, and I rely on Emacs VC to drive the tool.
On Solaris hosts, including locked-down "production", I use SCCS to version my dot-files because it's available by default. For development I use SVN (old too by today's standards).
I don't advocate using these old tools over modern alternatives; however I find their simplicity in the above cases to be beneficial.
I used to use RCS, but these days I use mercurial. Pretty much any DVCS is going to be a "better RCS" than RCS (bzr, mercurial, git, fossil, monotone...). Even if you never need to pull/push.
