Plug-ins can add massive amounts of entertainment value to a web site - visitor numbers, latest comments, "Bad music I admit to listening to", the time on Mars... but sometimes the flashy features can slow your site to a crawl, destroy the formatting, or add nothing positive to your site, whatsoever.

A poll plug-in that went horribly wrong

Polls are a good way to get visitors to interact. What is the saying? An opinion is like an asshole, everyone has one. Well, I would like to talk to the asshole who wrote the poll plug-in that wrecked our web pages in Firefox.

Unique plug-ins are few and far between

You have to have something special if you want to attract visitors. So that cuts out the ubiquitous "Press the fart" button, or a drag and drop Zwinky (get a life) avatar tool bar. Everyone has one of those, right! I came up with the idea of an "I'll guess your weight" plug-in, but I am yet to find a way for visitors to sit on my face.

Worst ideas for a plug-in.
