Originally from a Joomla! background, Drupal has been recommended by several peers. I've been really impressed with every aspect of Drupal so far; so much so, Drupal is now my default CMS platform.
I will be applying for a CVS account soon and (if approved!) contributing some themes back to the Drupal community.
GoPro is a new drupal 6 web portal. Based in Israel, it is aimed at suppling answers to common questions that people ask professionals. Questions that are getting answered on a daily basis. Professionals open private Blogs and update promotions, sales and How To's articles. People looking for professionals can use the search engine to find professionals next to where they live. The search module arrange blog posts based on relevancy and the ammount of cooments given in the choosen posts.
This was the first site i did with Drupal (right at the bottom of the learning curve!!) and turned round in a few weeks as my cousin hastily prepared for this epic adventure....quite a simple site but beginning to get good results now and all its followers have very much enjoyed keeping in touch with Rob. I would do things very differently now, as this was before I knew about views, panels and cck! I'll be adding these in over the coming weeks though...
