* I like the \ for forcing a newline * I think four hyphens, no more, no less, should translate to <hr/> (i realise your proposal is not different from current syntax)
* I don't like that your image syntax is like <<image foo.png>> instead of <image:foo.png>, this is inconsistant with the rest of the syntax. * I'd like «« an »» better than << and >> * I like the syntax for **boldface text**, //italic text//, $$typewriter text$$, ^^superscript^^, and __subscript__.
