At the time android didn’t have multi-tasking
Android always had multitasking. Part of the issue with android 1 and 2 was that it didnt have any way to properly manage the task managers which lead to people installing task killers(which had utility in those days) and auto task killers(which due to how android handles caching just lead to a cycle of killing, thing popping up, killing, and etc). My g1 with a swap partition was probably my best android phone at keeping things in memory without auto killing it until I got a phone with 6gigs of ram.
I still browse reddit, honestly more than I do lemmy, but its mostly reddit old with adblock. Even on browser even though that is painful to navigate.
With properly curated subs its not so bad, but there definitely is still something missing. Also holy cow the current algorithm on reddit is trash. It used to be that the front page changed and shifted but sometimes I see the same crap on my front page for 2 days. It’s insane!
