I don't go in person to the library super often any more, but when I did I got in the habit of grabbing one book semi at random off the shelf. I say "semi at random" because it's probably from a section I enjoy (likely fantasy) and I'll quickly vet it as something I would at least possibly enjoy. But otherwise, just grab a random thing.
Pair that with a willingness to stop reading a book if you're not really into it, and sometimes you find gold where you'd normally not have thought to go looking. (A willingness to not be stuck with a book can go a long way toward making it easier to start one, in my experience.)
Gastronauts has done a casting call for season 2 already, and I think the loss of PIBE had less to do with other shows taking its spot, and is more just on its own merits. It either wasn't successful enough on Dropout (where so much of the marketing is things like insta/yt shorts/etc.), or Zach and Jess are prioritizing other things, or some combination of both. I don't think anyone official has really said. (I'm not even sure we officially know there won't eventually be a season 3.)
I definitely miss PIBE personally. I thought season 1 was pretty decent even though it got pretty badly panned in general, and season 2 was incredible. For what it's worth Zach and Jess did a 300 episode podcast called "Off Book" which is similar vibes.
