Try something new.

Newly available: Supported across the Baseline browser set.
Widely available: Thirty months since becoming newly available.
Limited availability: An opportunity to explore, with care.

That's the next step: try something that's not ubiquitous yet. Look at what's becoming available in browsers today. Take a look at release notes and "Baseline Newly Available" features. Pick something that looks useful and experiment with it. If you're not familiar with Baseline, let me explain briefly. Baseline is a computed status that's based on web compatibility data, and it quickly tells you whether something is supported in all major browsers or not, and for how long. It gives you a sense of stability. One great way is, of course, MDN, which displays Baseline banners at the top of most pages. But, here's another site that's based on the same data: the Explorer. You can use it to list the "Newly Available" features, meaning those that recenytly became available in major browsers. If you're feeling even more adventurous, look at the features with limited availability too. Try them. Push them. See where they break.
