Curious, I haven't heard about Overleaf so what's an advantage over Sharelatex (OSS)?
- Rich text mode on Overleaf makes it a lot easier to collaborate with colleagues who would otherwise be put off by a wall of LaTeX code.
- Automatic compiling on Overleaf - you don't need to manually hit compile, we do it automatically. This makes it easier for authors new to LaTeX as errors can't build up
- Unlimited collaborators - share the project with as many people as you like.
- Direct links to publishers to help streamline the submission process for academic papers.
Feedback always very welcome! Lots of different ways to approach this, and we're continuing to build and improve on the service.
I believe a more practical feature is adding roles! I mean Editor,Co-Editor, Publisher, Copywriter, Professor, Examiner, Teacher etc. all of these have different jobs, although very similar they do different things. If you give these poor guys a UI or Workflow, that'd be great I think.
Well, if you need a killer argument to sell your product, you'd have to be able to say:
"You write alone or together, we proofread, suggest media, translate, publish, print or schedule submissions for just n$/mo."
Ok, you'd have to integrate external API from ie. commercial online newspapers, qualitative semantically fitting graphics, smart autocompletions with professional "sentence snippets" and so on. Most important thing is to sell it to universities though imho.
