I am using the CMS web to date 6.0 since 6 weeks to create a footballclub website. The functionality is great and I do not go into details. Visit therefore todate.com. My experiences are mostly positive:
+quick adjustment for the complete workflow and perfect for small business
+many customizable options for creating individual websites. You can insert videos (youtube, flash, flv), audios, pictures or feedback forms, for example, very easily to your website
+SEO: page titles in url, use of meta-keywords and meta-discriptions
+no monthly fees
+no programming skills are required

-navigation levels are limited to 3, but enough for most small businesses
-you cannot change the color of the black frame among the videoplayer who describes the video content
-not free

Conclusion: web to date offers many options for a professional online appearance and I thick it is quite good for smaller business companies but not for big ones.
