I find it weird that your point against org-mode is "too much lock-in".

It is a plain text format, which looks good even wherever it is viewed.

Pandoc even supports org-mode[1], which should let you convert an org-file to say markdown if you want.

sure, only if you stick to bare-bones org-mode. if you start using any of the "power-features" unique to org-mode you're stuck. If you restrict yourself to markdown-compatibilty, why not just write in markdown?
