Before you get too carried away with the VSS bashing, it's worth
pointing out that any VSS users with any kind of sense, are not using
the VSS client, but rather SourceOffSite server. This gives you
protection against the "pulling the network cable out" problem and means
that all access to the repository is synchronised, so lessoning the
chances of collision corruptions. Indeed, it's the only way to work
with VSS over the internet.
It doesn't protect you completely from problems inherent in VSS, but it
certainly makes it very useable.
In 10 years of using it with VSS, we haven't had a single corruption or
issue manifest itself.

Ah, VSS bashing! Can't resist to join...
VSS, by design, depends heavily on well-synchronized system clocks of
all client computers performing checkins. In the worst case, your VSS
database is trashed completely simply because one computer checks in a
change while his system clock is on a time *before the VSS project was
created*. The main lesson to learn from this is: You can simply not
trust the VSS history because all timestamps reflected in the history
stem from the system clock that the client computer had when the checkin
was executed.
The MSDN says to this: "Make sure that you synchronize the dates and
system clocks for all Visual SourceSafe client computers".
Some development teams (such as ours here) frequently need to fiddle
with the system clocks of their computers for example to test software
behavior that depends on timestamps etc. So if the developer forgets to
re-adjust the system clock before checking in something, the VSS history
might look funny thereafter.
