Are People Really That Mean?

I've started looking at other blogs on blogspot and occasionally run across one that's interesting, funny or well-written...and add a comment. Okay, my comment might be a bit humorous in a slightly sarcastic way. But I consider a comment on my blog a compliment that I said something worth responding to. But OMG these people are really hateful, like I'm invading their precious blog world.

HELLO??? If you don't want me to read it, put it in a diary with a lock on it!

I thought that was the point of these things...to put your thoughts "out there", build a readership and create some buzz. Instead I'm sent running and screaming from their blogs, hitting the delete button on their site address as fast as my mouse finger can fly, never to return again. I just don't get it.
