I've been fooling around with the beta and found out out how to make the posts come in like they used to (as well as possible).
1) Go to explore tags and only add the the ones you would actually be interested in.
2) Sort by: Latest
3) Created: Month
OPTIONAL: If you really want to go out of your way, every time you want to look at a specific topic, unfollow all the others except for the one you want to view.
There is no real way to make it perfect, but hopefully this makes it feel more like home. :)
