I have written about Leonardo before, but now I am implementing a site using it for real.
For previous thoughts see 42: Leonardo, 42: Designing from the Outside In and 42: Composing WSGI Apps.
Anyway the site will be for the Raunds Methodist Church (nothing to see for at least a month) and I have been finding Leonardo a superb environment. It is really simple to add content and alter the design (within limits, although those are being push back all the time). Plus James has many of the same ideas and needs as me so it moving it in the right direction at the right time.
If you have a content rich site to produce which does not need to be to amazingly fancy in terms of graphic design and which needs to run on any hosting platform even the really lite ones then this might be the right tool for you.

Hi Mike,
having only looked superficially on leonardo (don't want to look into the source) I found it very hard to understand what it can do. There's virtually only one sentence of feature documentation. Also the look of the leonardo site is very minimalistic (I wouldn't want something like that for a client). I think textpattern is far more interesting being although an opensource wikilike cms with blogging features using textile markup (although it is written in PHP, but here in germany I can find hosting for PHP and MySQL for 3 Euros per month with a traffic flatrate. Being a python fan myself I couldn't find something remotely similar). You can take a look at examples of TXP sites here: http://txpmagazine.kbbu.de/all_sites/
And the TXP homepage is here:

BTW.: Myghty is really nice.

Oops, the first "although" should be "also".

Mike,
I wanted a Python solution as I much prefer the language for working myself and I know there are things I am going to want to do whatever solution I choose.
I realise that python hosting beyond cgi is not so simple, but I believe that will change as WSGI servers become widely available.
I am concerned about security of php given the recent issues in libraries.
I found Leonardo very easy to start, download and with the readme you are running locally in a few seconds.
