We have ranks for combat, trading and exploration what about some additional minor ranks maybe similar to reputations which might be issued by their respective trade guilds or something like that. I'm thinking of maybe mining, bounty hunting, pirating etc It only seems fair really and it would be an extra set of goals to work towards without too much extra work on the part of the dev, especially as some of these are already shown it terms of credits in the information screen as it is.
