I have made a proposal at
http://meta.wikimedia.org/wiki/Wikimark2 for
a Wikimarkup v2. I was unsure where to mention that I'd made this proposal.
I am also aware that an update to syntax isn't pertinent or desperately
needed; nevertheless I'd like feedback on the ideas from the community. Like
Wikitax, the proposal can become a non-MediaWiki-integrated language on its
own, or, if there is support, it can indeed be the next base of MediaWiki
wikitext.
Disclaimer! I'm not being a "noob" with funny ideas that disrupt
unnecessarily - I would probably have thought that of me if I saw this
post straight-off - I've just had what I believe is a good idea for a
MediaWiki syntax which, regardless of status-quo, I thought might be
interesting to some of you. Let me know what you think at my Wikipedia
user:Alfakim.
