Absolutely! I've been using Evernote for years, it has served me very well. However, I recently thought that it would be great if I could use Evernote for importing/exporting Mardown documents. Personally, I've got so much invested in Evernote that I can't just migrate to, say, Gitbook or Bear (which look great, BTW). I would much prefer if they added a feature to import/export Mardown documents. I would manage the revisions with Git on my own.
It should be relatively simple, I suppose. Why not cater to this need? As to "how many people" are going to ask for Markdown well, obviously not that many, just those that code. Initially. Because Markdown is picking up quite a following...
I guess it's fair to say we all appreciate the product very much. We wouldn't even waste our time here, if we didn't believe in it. It sucks to be ignored. Don't ignore us, Evernote!
