First of all, what Jay said
Second of all, I was trying to find if there’s a user-selectable view for homepage presentation (besides a global default for everyone), and haven’t found it. People always ask about it, though: https://meta.discourse.org/t/user-selectable-default-home-view-preference/12816/9
In all our research - including on the link above - it’s a 50/50 split between those who like the “All Posts” and those who like the Category view.
One of the possible solutions mentioned is to set your bookmark to the forums to go directly to Category view, if that’s the one you like. Bit of a workaround, but most of the time should give you the result that’s best for you…
