I've seen the abbreviation "SF" used in a couple different questions recently, both here as well as on Meta Stack Overflow (the network meta).

At first, I though the poster was asking about Server Fault, which is generally abbreviated as "SF".

There is the potential for a lot of confusion if this catches on?

Therefore, what is a more appropriate and less confusing abbreviation to use for Salesforce Stack Exchange so that it doesn't get confused with Server Fault when discussing this site elsewhere?
