I think we are forgetting that Wikisource is a WIKI!

>This is not the question ; as I said : who decide what is a good 
critical edition ?

The community decides through collaboration and discussion.
We are a wiki.

"The quality of an encyclopedia cannot be based only on what contributors
think to be good. This is a circle, and that doesn't make Wikipedia reliable.
That is why Britannica is a much better idea."

We are a wiki. In any Wikimedia project, the community needs to think about and
decide how it can best serve the public. The rules that define Wikisource are created
by the Wikisource community and such things are discussed (which is what
I hope we are doing here).

So go argue with 8 years of experience instead of trying to learn from it... :-)

Have to go...
