Some of NPR's podcasts recommend visiting their website for more information.  They say, "Please visit N-P-R dot O-R-G."  Every time they say it, I think, "It's 2009.  Just say 'org.'  If people don't know what you're talking about, they probably don't know what the internet is." 

I also hear people say "forward slash" when they're referring to subdirectories of URLs, as in, "google dot com forward slash search."  First of all, most modern web browsers automatically correct for that.  Second, if people can't figure it out by now, they probably shouldn't be using the internet.  Thirdly, I still don't know the difference between a forward slash and a back slash, and look at how far I've made it in life (on an unrelated note, I'm writing this from a bathroom). #technology
