I'm pretty much the complete opposite. Veeerry infrequently I might peek from a mobile browser but 97+% of the time I'll be interacting from Safari or Chrome; in fact I can't think of a time I've actually made a post from my iPad (and wouldn't unless I had the bluetooth keyboard going in which case I'm halfway to laptop).

Might be interesting (and someone's probably done so in the past) to look at the user agent info and see what people are actually using rather than anecdotal self reporting.

For completeness: I heavily tweaked my user experience with several CSS and JS extensions.

Last but not least does my wiki-syntax facilitate posting a lot. (see Wikisyntax for the Monastery)

needing to type html-tags with a mobile would be a no-go.

My point being: it's perfectly possible to use The Monastery from a mobile in a useful manner.

It's a pain and one that should be un-necessary. If the code that parsed the input assumed that everything without any markup was actually meant to be in <p>paragraph</p> tags, that alone would make posting and commenting on mobile much easier.

The parser already checks for missing tags so it is not too much of a stretch for it to be able to guess which ones need adding. Perhaps with more rigorous enforcing that the contributor checks with the preview.

That would be very interesting, especially plotted over time!

I know it is totally different and not really comparable, but one of my company's websites is currently 62% mobile visits compared with 54% in September 2018. The other main site we have is 87% mobile. I have no previous data to compare as it only went live earlier this year. The high mobile on this site is probably due to driving traffic from Facebook with paid advertising.
