I think the problem is, most sites don't have the extra big traffic or the massive good linkbacks the big sites have, with which they can use to survive, so it is easy to panic. When your making "descent" cash, a drop can make a pretty big difference.
I didn't mean to start this thread to start a panic or say there was a panic going on. Just more and more people "talking" about linking being the problem. I did get e-mails from people letting me know, which is the way to do it, they know who they are..
But I also found some that didn't say a word. Just more a reminder, it's best to let people know before you drop their links.
