Its included in nearly every *nix system and generally syntax is much easier to handle (a doc with no syntax embedded still produces reasonable results).
Notwithstanding the wonderful 'mom' package, its shame development has seemed to dry up.
I had my troff phase, but I don't see why I'd want to write troff directly for simpler documents if I can just write in org-mode or Markdown and convert it to a myriad of formats (including LaTeX and HTML). With org-mode I can also run inline code snippets, feed tables directly to gnuplot, use org-mode's todo/agenda functionality, etc.
For simple projects I do not even write tex code directly. I write in org-mode and export. So I wouldn't be opposed to using groff for typesetting if it produced high quality output.
But whenever I'm preparing for publication I always end up manually tweaking many things for latex. There are a lot of things TeX does automatically perfectly well. Typesetting paragraphs is one of them. But overall page layout always requires manual work in my experience. Does groff make this manual work easier?
To recapitulate: the end of the graph shows the value for the final date on the x-axis as zero. This gives the appearance that the graph has been rotated a few degrees anti-clockwise.
Of course, the collaboration features of ShareLaTeX and Overleaf are great. We wrote two of our last papers with Overleaf.
The way we pay practically $0 for infinity authors and projects is, we have only one payed account and this one invites everyone else.
One thing I miss is the annotation feature google-docs provides. However, the /todo packages is kinda helpful.
Can't recommend it enough!
I had a quick look at ShareLateX in order to help my sister with her latex experience. While I can not say anything about larger documents, the ease of DVI previewing in the browser, etc, it for sure gave me the opportunity to debug some of her code in small pieces, test out LaTeX example code, and share the results with my sister.
Nice project - best of luck and keep up the good work!
