Cheap Cable
I learned something at work today. We were switching some DS-3 stuff around. The whole thing got shutdown by some cheap coax cable, that didn't get crimped right, or got shut in the door or something. The point of the whole thing is this? You are only as strong as your weakest link.<br />

Everbody knows that saying, I know, but how people apply it. I think of this in terms of web apps. If there is a weak link in something, even though everything else is great, people wont use it, or worst, they will use it and call you asking you to help them make it work.
