can websites last forever?

[Stone]

I can't tell you how many of my saved links go "bad".
I have a website myself, and I like to post links to good information... and I should back up the information by downloading the sites, because I often go back and find nothing.

There's a broken link checker addon that you can add to your wordpress blog that will notify you every time one of your links go bad...

Why do links go bad?
Usually... it's because the webmaster got tired of paying for hosting, or the free webhost went out of the free hosting business.
