Konqueror and plugins

Konqueror is getting some great, very recent, reviews, but the reviewers always downgrade it because, they say, there are no addons or plugins.

However, there is a blog post on this site showing not only are these available, but also there's a way of converting Netscape plugins to use with Konqueror -- here:

I see the conversion application (also linked on this site) is compiled for Hardy (by now, a bit old) but yet, there is mention that it's for KDE4, and that's still in use. Is there a typo here, or should the .deb run OK in a current Kubuntu??

Please reply with details if you or anyone you know is actually using any of the Konqueror plugins/addons listed on the linked page, above.
