Ask HN: which WYSIWYG/Markdown text editor do you recommend?

Pagedown is the Markdown editor that Stack Overflow uses. I've used it - nothing fancy, does the job.

not really sure what your specific needs are but we built http://etchjs.com in the absence of finding a wysiwyg we liked.

I am 60, and what is this?

Text Editor: vim

Personal Markup: Something close to Creole

Data markup: JSON or CSV

Also, ndb reminds me of LDAP.

for what use? e.g. a desktop one? or an online control? if it's the latter, CKEditor seems like a trending one, and WYSIHTML5 seems the most starred on GH. but not sure I understood your question.
