What do you mean by outline? Maybe there’s something in my head, but I’d like for folk to tell me what they think ought to be the content, the purposes, the problems to be solved, the scope.
There’s nothing that I intend on keeping private.
Collaboration infrastructure gets built as needed. I don’t do big requirements and design up front.
I’ve got everything in my head. The time it would take to write it all down, I might as well just jump in.
Github does not apply here. It is just barely enough content easily maintained, it should just be about giving it a little fresh coat of paint once in a while to keep it lively.
For a site to look “alive”, it ought to show activity. The activity comes from everywhere outside the portal.
Changes to the web pages? The idea is: extremely rare. That’s the point of a portal. It just brings together content that is actively maintained elsewhere with whatever is the best tool for that job.
That’s the point of choosing Google Sites as a portal. There isn’t supposed to be much in it. It is just supposed to show in one place stuff that is all over hell’s half acre.
Future-proof? No such thing. Easy to recreate anywhere else? Absolutely.
EDIT: The idea of this portal is not to replace anything “out there”. It is about showing everything that is out there (or at least linking to those things out there that cannot be embedded directly in the portal.
