1. I bet that most of web developers on this forum do not use IE as their primary browser and therefore do not need any extra popup killing software.
2. People are much more likely to check something out when you provide a link to a demo page so that they do not have to waste their time pasting your code into a test page.
3. Those whose opinion worse anything, try to avoid popping up widows unless absolutely necessary (which is usually specialized applications, never a regular web site), therefore they do not really care about such code.
Solution to popup killing software is not using popups
