After all, the main thrust of Kotzk is said to be Emes, truth, and that is not a Chasidic thing, it is a general value (or should I say general Jewish value?), that appeals to Litvaks as well. Especially perhaps to those into mussar.
Anyway, the other day I was surfing around and came across a Kotzk blog! I sampled it some and found some good stuff there! So you might enjoy it as well.
It is from South Africa, yes, that country that gave the world The Shabbos Project.
Anyway, in case it interests you, you might want to check it out.
