As I look at the viewers of the family blog, I can see that more and more people are consuming the content from mobile platforms. From the report I pulled up from Google Analytics you can see that the total Desktop readers fell from 71% to 57%; most of them are now replaced by mobile users, both tablets but mainly phones.
I do all my blogging from my PC, so I consume, and see my posts from a desktop perspective. Have you checked how your website looks from a phone?
If you come to your site and it looks terrible, fix it! The easiest way is to use a theme that recognizes your screen, not only if you are using a mobile platform, this way people will always have the best experience depending on the devices they are using.
