The difference between ChemSpider and WiChempedia, for now, is the presence of the first paragraph of the Wikipedia text on the WiChempedia site and a link out to the original article on Wikipedia. An example is shown below. Notice the link to the GNU free documentation license .
Hopefully we will receive feedback on the site quite quickly and get it out of beta at speed so please do let your colleagues know about it. We will design a new logo header shortly and we are aware that some minor types of the data resulting from the scraping process have slipped in so we will resolve those too. An example of how much information is starting to be populated can be seen by looking at the record for Cocaine here. Here you will see the Wiki first paragraph content, a link out to a GC run on the Phenomenex website, a series of validated identifiers and an IR spectrum. The content continues to expand as we source more information
I also point you to another implementation of a Wikipedia chemistry system, chempedia.net, that you might be interested in reviewing.

The open access movement:
Putting peer-reviewed scientific and scholarly literature
on the internet. Making it available free of charge and
free of most copyright and licensing restrictions.
Removing the barriers to serious research.
