I really like them. It's sad that they are rarely used these days.
I do too. More recently though, for some reason, most text chans/boards end up a harbor for shitposters. 4chan, Ota-ch, 4chon, et cetera-tier shitposting. Wish they were more popular myself, but the increased community would only make the site worse unfortunately. Some more popular textchans I know are Tablecat, Sageru, and World2ch. Channel4 BBS is a pretty big hub for text boards as well, though not as much traffic. It is also a dying breed, 4chan bbs was taken down, and I believe 4x13 has also taken a similar hit.
