Lance Leventhal is one of my favorite authors of machine language books, he wrote a series of books on old school microprocessors, each of which followed a fixed template and taught you the basics of yet another processor in a familiar setting.
One of the lines from those books that stands out very clearly 25 years after reading them last: "If a variable is tallying the number of horses name it 'nhorses' not 'qdogs'".
Names matter. So if 'CURRENT' means 'MAYCRASH' name it so.
-CURRENT is called CURRENT because it reflects the CURRENT development efforts and their CURRENT state. Of course it may crash. When it stops crashing, it's going to be released and that's how it will be turned into a RELEASE.
There is literally (and I'm using the word in its proper sense, not as a hyperbola) no way you end up with FreeBSD on a server without knowing this. No one just installed it "by mistake" in a production environment or mistook it for a STABLE version.
"Head" is very commonly used because it is from the language of revision control systems. CVS, Subversion, Perforce, Git, Mercurial, and probably others all refer to the latest checkin as the "head". It has a specific meaning to a much larger group of people than just FreeBSD users.
