My site, running Drupal 7 (more precisely, 7.14 at the moment), is at http://kozub.in.ua.
I kept thinking for a while whether I should post it here. All in all, it is a very simple website, without fancy visual design. (In fact, it uses Stark theme, i.e. absolutely _nothing_ interesting on the visual side :).) On the other hand, it may be a good example of the power of Drupal being used by an independent professional, who is not a Web development pro etc.
Before installing Drupal, I had a website consisting of several static HTML pages I coded manually. Every time I looked at it, I thought "OK, time to either kill it altogether, or to start some development and improve it somehow". One of the key reasons for the site to remain in that “hanging” stage was was not about technical difficulties. I am quite well-known in my professional area, so from a business development perspective, I just did not feel a strong need to develop my website. However, I finally decided to start this journey, which is still at a very early stage :). I also decided to add a separate section for my personal stuff, like mountain trekking, a personal blog, etc. (That part has not been published yet, but I have been working on it.)
