Hello there!
Once again I must admit how happy I am to use Inkscape - it has become no. 1 application that I use - see the attachment if you need proof ;-)
Here is the list of example sites created by me, that use graphics by Inkscape.
http://artemio.net My home site. The interface has actually been drawn in sodipodi (as I didn't know about Inkscape when I was creating thisone), but the rest (the icons on the main page etc.) is all by Inkscape.
http://artemiolabs.com My audio laboratory site. 100% Inkscape.
http://lilija.com.ua (in Russian) The site of a florictic shop where my sister works. 100% Inkscape.
Note: all images were cut and JPEG'd with the GIMP (you guessed).
Also, you guys mentioned that we, the users, can send you the screenshots of how we use Inkscape? I think it would be nice if, for example, you create a page on your site with a screnshot showing Inkscape at work and the web site that uses these graphics. If you need such a thing - just tell me.
Thanks again for the best graphic editor ever and happy development!
Artemio.
