4chan will never "get better" because if that happens it'll cease to be 4chan as we know it. /b/ has always been an open pit sewer that the occasional nugget of gold flows through. /trv/ is where I like to hang out, but /pol/ can't help itself and likes to crap-post in there on the regular. /gif/ and it's blue board, "safe for work," version /wsg/ are fun to browse, but the 4chanX extension and some filters are needed to hide a lot of the trolling and truly awful stuff while browsing.
