Thanks for taking the time to check it out, I will look into what I can do to improve those issues. It’s basically impossible to get usability insights like this when you’re the only person working on something, so this is much appreciated, thank you!

I’ll use this comment to address some questions I’m getting on the demo:

Why not a wysiwyg rich text editor? Markdown is for nerds like us. Comments are for all.

Simple reason is that a plaintext markdown editor was easier to implement. I decided plaintext was “good enough” for the kind of site Confab is intended for. If there is enough demand for this, I’d be happy to look into implementing a better editor in the future. Edit: The current editor has graphical icons for all the rich text features which automatically inserts markdown snippets, so even a user who doesn’t know markdown shouldn’t have too much trouble using it.
