Assuming too much... People who conplain loudly about ClearCase most often never understood how it is supposed to work. Ok ok, you need an army of administrators to make it work but still far from being the worst.

Sourcesafe?

"most often never understood how it is supposed to work"

This is a BS argument.

Yes, everybody got it wrong, Git is wrong, SVN is wrong, it's CCs broken model that's correct.

" you need an army of administrators to make it work"

Yes, let's sink an awful amount of money in a half-baked software that needs all kinds of 'helpers' to work properly.

Personally I won't work in a company that uses CC anymore, and it's been only bliss since then.

Sourcesafe is bad, but it's a different kind of bad. And it makes even CC look good.

I don't have any experience of knowledge of Sourcesafe, but it wasn't in the original list ;-)
