One rule to live by:
In the 15-odd years I've been doing client-side web development, I've seen precisely one piece of script on the internet that worked as advertised and was durable enough to consider including in one my projects. That exception to the rule is jQuery itself.
jQuery plugins, however, exemplify that golden rule. Every time I've tried to use one (being a hopeless optimist and breaking my own rule), I've been bitten hard and ended up either rewriting it from scratch or spending more time trying to get it to work in a reliable manner than it would have taken to rewrite it from scratch.
