I really like sites that do one thing really well. My site, for instance, doesn’t. I blog all over the place. It’s pretty eclectic — HR, government, movies, TV, astronomy, recipes. It reflects my life, and I could probably grow it a lot faster if I’d pick one little niche and do it well over time. On the other hand, it’s fun for me, which is a key ingredient.

However, I admire when other sites do something really well. Like http://www.responsinator.com/. What does it do? It tells you what your website will look like on various mobile devices (heavily geared to iPhones). Think of it as your own little beta tester for web design. As of time of writing, you put in your URL, press GO, and it will show you what that site (probably your own) looks like on:

• iPhone 5 portrait · width: 320px
• iPhone 5 landscape · width: 568px
• iPhone 6 portrait · width: 375px
• iPhone 6 landscape · width: 667px
• iPhone 6 Plump portrait · width: 414px
• iPhone 6 Plump landscape · width: 736px
• Android (Nexus 4) portrait · width: 384px
• Android (Nexus 4) landscape · width: 600px
• iPad portrait · width: 768px
• iPad landscape · width: 1024px

If you create an account and pay, you can choose which devices show up, you can host it on your own site, etc. I use WordPress and it’s new custom themes option gives you some ideas of that already too, but it was nice to see a different version. For me, it is more about tablets than phones, I think I’m too verbose for phones. 🙂
