Sam Ruby: "One key problem that we identified was the wiki syntax - both from a learning curve point of view and from a wiki tool lock-in perspective. It would be really nice if we could define a unified inport/export syntax that tools can use, either to PUT data to a wiki, or to migrate data from one wiki to another.
An obvious candidate would be (X)HTML, as every wiki provides some form of export to (X)HTML today. The problem is import: one should not have to implement a renderer comparable to IE or Mozilla to do a credible job. A profile or subset is called for."
