I have a pet peeve with some stumblers. These are people who send me a message asking me to look at their page and give it a thumbs up if I like it. I look at the page and give it the thumbs up and attempt to send a reply to the personal message and receive a message from Stumbleupon that the user's inbox is full and the message is not deliverable.
If a friend wants me to look at his/her site enough to send me a personal message then please have the courtesy to read your own inbox and clear space for replies from me. I don't like it and I do not stumble for those who repeatedly bounce replies from me because their inbox is full. End of rant!
