You want annoying? Old people who discover email and know your email address. Now- THAT'S ANNOYING!
I am the computer consultant to the old folks at my Mom's church. I advise them on what to get, set it up for them and show them where to go to get free training. I make a little money by fixing things they botch up and keeping them running.
Once they discover how to use email, I get recipes, cute grand baby pictures, forwarded jokes and all sorts of geezerspam I don't want. And I've got to look at all of it because in the mounds of crap are occasional requests for services.
Upside: I'll soon be publishing a collection of ten-thousand casserole recipes.
Downside: I hate ALL of them.
