You know, I laughed out loud, and then I saw the irony in that type of context-sensitive advertising. That's something those clever marketing types and software developers do to target their ads. Mighty clever, huh?
It's an ideal tool if your job is to corrale the online "masses" and get some of them to show up in your web-doorway. Bad, if you're one of "us" who hates seeing those ads. I know how it certainly helps to keep costs down and makes it possible to run this web forum without charging an admission price, though.
