I believe linking hubs is still a good way to gain traffic to your hubs.
Links though should be used sparingly, try to link hubs of similar subjects, so if you write about holiday destinations link those hubs, creative writing create links between those hubs. You might cross link a hub about a holiday destination with a creative writing hub, but Google doesn't like that much because of the question of relevance.
So yes link hubs, use links sparingly and try to keep them to related subjects. But don't let Google ranking cramp your writing of hub subjects, letting Google dictate your work is not good for you. Write what you are passionate about, then let Google do what it wants with your ranking.
