In tabbed browsers, clicking a link with the middle button opens the link you’ve clicked in a new tab. This is a useful piece of functionality.
If you set your web page up to get round this feature, so that clicking the middle button opens the link in the same tab as the page you’re viewing, that doesn’t make you a clever web guru. It makes you a fecking idiot.
