Why is Mario Vargas Llosa, NEVER discussed in this sub, and who are some other academically important writers who are not popular?

MVL is inevitably one of the Golds of Latin America, regardless of his absolutely beautiful books which are on the same league with Marquez, the guy has won a Nobel in literature and is a Member in BOTH French and Spanish Academy, So he is academically well regarded, yet he is never discussed in reddit specially compared to his peers like Gabriel Garcia Marquez.

among other writers who, In my idea is extremely important yet less discussed is Rumi.
