it's chronological, what you see is what's being posted or boosted in real time, not ai/algo driven as seen on the #birbapp or elsewhere
you should see the top two pinned posts at @feditips, you'll find those helpful
going forward you'd probably want to add alt text to screenshots and images, people are more willing to consume those posts
and add as many hashtags as you can fit :)
in lay person term it's probably moot :)
@chadnotchud People like to talk about "The Algorithm" in respect to social media - the tracking systems that generate your personalized feed and choose who will go viral, and who won't. It doesn't really take that much for it to become just another meaning of "an algorithm".
This is in case if you really don't get what they mean and aren't just being pedantic.
