How do I add topics to my profile with the new design?

This is a little bit of a weak point for us right now. We plan on adding a much easier and direct way to add topics to your profile in the near future. Right now you can do it anytime you see a topic on a question (or anywhere on the site) just by mousing over that topic and clicking “Add Topic” or you can wait for a few more hours and see the magic new feature we’re launching and use that.

@timtrueman In a few hours?! I’ll be here!

The above answers are true and I also learned this method for adding topics.
