Awesome seeing someone use the reddit dataset :)!

Wouldn't a w2v as a recommender for the user might have been better?

Taking user's comments/likes/subreddits as a feature.

I think your thinking of just a classic collaborative filtering recommendation system.A simple w2v system would take into account all words, then have to be filtered by words that are equal to subreddits. Although, I may have misunderstood your suggestion.
