Not sure if this has been posted yet, if so forgive me.  Did a quick search and couldn't find anything related.
So a personal pet peeve is all of the junk mail i receive and advertising crap left on my door.  The worst culprit are those thick useless yellow page books I get every now and then.  Do people still use the book?  Eh, I'm sure some do, but I sure don't want one.  It goes straight to the recycling bin.
For anyone who is interested, check out the following site:

Forgot to mention that on this site you can opt-out of receiving yellow and white page directories.  I guess that is kinda key.  Too damn busy; no time to think.  I opted out.  Now, to get rid of the people that leave ads on my door every day.
