I was beginning to think I had gone mad, or perhaps there was committee that changed the spelling of "lose" without telling me. I honestly haven't seen anyone spell it correctly in months.
This has been driving me crazy, too. When I've complained about it to people who don't primarily read text generated by techie-types, however, my rants have been met with vacant stares. So maybe it's a nerd thing.
I had an office-mate in graduate school - he's a mathematician now - who complained that he could never remember which "oo" sounds required only one "o" and which required two. He was constantly prooving theorems involving smoth functions.
