That's why it's important to only use acronyms in their context, or provide the context when using them. And for goodness sake, expand them on the first use if you're audience is not already familiar with them! (and really, even if they are, it's just polite)

Yeah, the TLA (three-letter acronym) space is vastly overcrowded and most TLAs are overloaded. This goes double for TLAs (two-letter acronyms). :P

yes. TLA and XTLA overloading is a real problem, particularly when going cross domain.

Maybe we should insist on some standardised expansion of TLAs and XTLAs so you know unambiguously what any particular Three Letter Acronym or eXtended Three Letter Acronym means. I wish I could think of a way of doing that...
