All of my Moodle's are development ones, so only me reading them... but.... the themes I develop have places for marketing spots, carousels, horizontal block regions, alerts etc. So a place to put generic information to be seen by all before logging in and getting their dashboard with more personalised content. So if you're using Moodle to sell courses then it is a good place to advertise them, for example: www.moodlebites.com run by HRDNZ, a Moodle Partner.
That’s an interesting point that I didn’t think of.
I always tend to have login forced as a requirement. This means the user lands on their Dashboard.
This makes the home page an orphaned destination.
It probably applies to many but I don’t sell courses. Hence, “what’s the point of the home page?”
