Interactive notes in a bottle

I have stumbled upon a company in Palo Alto
which is marketing products based on a convergence of wiki and blog technologies.

Socialtext Kwikspace
--------------------------------------------------------------------------
Socialtext Kwikspace is built upon the Perl/CPAN Kwiki framework.
Kwiki, a well-respected and actively developed open source wiki core,
is known for its rapid and simple install, modular design and open plug-in architecture.
Kwiki was created by Socialtext software lead Brian Ingerson.

Socialtext workspace
--------------------------------------------------------------------------
Socialtext workspace is for teams who want to get their work done better and faster,
with the convenience of secure hosting.

I got a free 30 trial account for "Socialtext workspace".
As soon as I find out how to use it, I'll let you know.
