What audience are you speaking to?
What are the users of this service?

Businesses, Non-profits, or anyone who wants to create or maintain a knowledge base on a particular topic.    Young businesses and non-profits may find Wagn an especially good fit because they can start without much structure and wagn will grow with them as their needs evolve over time.

We also intend wagn to useful for more more ad-hoc/open groups-- that's how we're using it on hooze.org, but this particular offering is focused on knowledge management more than social networking.

Where are they? How will they find you?

Geographical location isn't a technical issue, though it might be a marketing barrier.  We can promote the service at Conferences, through the NTen network, 1Northwest comes to mind, through our social network..   Techies can find wagn through rubyforge..

How do they pay?

Paypal?  I think that's all we've got right now.  should look into other options.

Why would they choose you over Ning and others like that?

Compared with Ning, Wagn is more more focused on the knowledge than on the community. 
Wagns ability to represent knowledge is it's strong point-- it provides many of the benefits of more structured systems,
in a way that's flexible and malleable, so you can organically grow the structure you need. 

Or why would they choose to use you over a wiki?
Then, very much related, what are the core benefits to using wagn?

In a nutshell, wagn gives you a lot more tools to create structure with than a wiki.
It also helps you visualize the structure and locate yourself in it by showing you multiple cards at once.


And will you service people who have one system and want to migrate to yours?

We've started on tools for import, which could be generalized to most wikis, but they're primitive.  For now we can offer migration as some combination of custom development and general wagn development.
