My company uses ClearCase, which also works by checking files in and out
(accompanied by comments, if desired) and preserving all earlier
versions. I find it easy to use.

In VSS the whole history of who has worked on the file is available
to every user, and you can compare any two files in the history, but
you have to be able to read the code and have an idea of what the
changes mean. Or you have to get your programmers to write comments
in the comments field of VSS. You can look at the history and say,
Hey Bob was working on that file. I can see he changed this line of
code, although I don't see any comments.

Yes, you're right it does still require interpertation.
