How is Markdown intuitive? It is completely arbitrary. Do you really think it makes sense to denote italics with single asterisks, and bold with the same symbol, just double? At least SchemeBBS is somewhat consistent, you use double symbols everywhere and the symbols are distinct. But SexpCode is not only consistent, but also straightforward. If you want bold you use b, if you want italics you use i. What could be more intuitive than that?
