Hi there,
i am a freelance web developer and i used to build my sites on drupal until about 6 months ago. I have now gotten into the habit of picking wordpress for 90% of my projects - it's truely awesome and became much more powerful since WP 3.1, then even easier to use with 3.3
I have recently launched
http://www.swissabout.com - a business directory running on wordpress.
You can see my other projects on my portfolio -
http://www.simonswiss.com
I guess this classifies myself as an "entrepreneur using wordpress" :-)
I'd be glad to share tips / suggestions with fellow wordpress'ers in the EF community!
Simon
