I'm a student. My homepage opens to italki search every time and the algorithm is strange for the past week.
"Every time that I search for a teacher of Russian, I get this Italian man, Fabio Oliveri. He is not a native speaker, has zero Russian lessons, and is not less expensive. Maybe he is sleeping with someone at italki because there is no reason for him to be #1 every time."
I have nothing against this Fabio, he's probably a nice fellow, but show somebody different. Maybe the algorithm likes him because he is available 24 hours per day (all green dots).
