i do a typing quirk 99% of the time because homestuck deeply touched me. I have forumul8d it 2 be minimally intrusive and mostly replacements or deletions instead of additions
currently:
all w's are doubled
to, two = 2
for, four, fore (as in before) = 4
ate, ation = 8
when i am feeling silly i will replace the word 'break' with '8r8k', even though this is a stretch.
i mostly do it because it is silly and lets me interact in a more authentic wway, imo. its fun 2 do and seeing the (mostly positive) react8ns 2 it is alwways fun!
