I never look at the Type and Category fields, my eyes are just not drawn there.
What I do look at all the time is the Mechanism field. That's one of the first things I check when finding out about a game for the first time. I also use that field extensively in searches. It's fun to do an advanced search for combinations of different mechanisms. For example what are some co-op trick-taking games besides Crew and Fox in the Forest Duet?
