I have not personally used any other GAE CMS than Vosao, but I though this might be useful for other people looking to enter the CMS in the GAE playground.
Lack of a CMS in the enterprise is like a disorganized woman’s purse. You will find what you are looking eventually, but most things will be gone forever.
First Vosao. Please refer to our last or previous to last post to read more on Vosao.
The list below represents all the CMS system that currently runs in GAE:
| CMS Name | Last Update | Amount of Downloads |
| GuteCMS | 5/25/2009 | |
| CPEDialog | 3/6/2010 | |
| DJango-CMS | 1/5/2011 | 595 |
| App Engine Site Creator | 2/1/2009 | 6,310 |
| Nuages Photoblog | 8/16/2009 | |
| Net-Fish | 3/14/2011 | |
| RicherCMS | 1/24/2011 |
Vosao or any of the CMS above does not represents an enterprise level CMS for a medium or big organization. Google App Engine, has no commercial grade CMS. You can easily start with any of the CMS above, but at some point you will need to move to a more commercial or at least popular CMS. A said this for a very single reason, support.
The reality today is, there is a niche to either built any of the CMS above, or start a commercially grade CMS.
Thanks for reading and enjoy clouding.

This is very true. Sad for GAE.
