Hmm, I completely agree for using space bars in English.
But imo, it’s probably different in korean since korean writing uses syllable blocks, so I can’t say I agree/disagree with Sangwoo since it’s not like I can understand lol. Maybe it’s comparable to using abbreviations in text and most people talking on the internet are usually aware of the lingo ykwim? (you know what I mean?) (=・ω・=)

Cause why can’t you use a space bar?
