Pretty much most of my freinds are tech-geeks, so most of my everyday conversation is dominated by such talk, no problem when all parties involved have at least a faint clue of what they're talking about, but when it's just a ill-informed group of teenagers, yeah it's annoying, but I can pretty much tune it out. What's really annoying is working with less technically inclined people who don't understand what they're doing, and mess something up, and then try to pass their personal mistake off with a technical sounding excuse (the programs broken and it's all the computer's fault, all I did was delete some....what is it...dll file). That's probably a bad example, but it annoys me to no end when people try to pass an obvious mistake off using tech-esque vocabulary they obviously don't understand. I'm generally a very patient person, but somehow that gets on my nerves :lol
I've definitely been there myself in my teenage years though, but in general, I try not to talk tech unless I know what I'm talking about (or unless a more knowledgable freind is educating me on a particular tech.)
I've seen LOL starting to pop up in public venacular lately too, even a few ads that actually printed out the word lol:-(
