This is an interesting project, however, as someone who administers several wikis, both public and private I honestly wouldn't give up control of the server side to the cloud ever. The simple reason is data control. I want daily backups of my wiki data. Can I do that with this?<p>Similarly, where's the source?<p>Where's the install for private wikis, such as a company's private internal wiki?<p>Where's the api so I can write plugins?<p>Where are the plugins?<p>What is preventing wiki spammers?<p>Can I theme this for groups?<p>I see that groups are 'private' based on my invitations to them, but how can I be sure this isn't easily compromised?<p>Anyway, this looks interesting, but I don't think it can be used yet for any serious wiki work.
