Hi,
I am also doing the same with my blog and Social media. I share articles I find interesting on Twitter. As you are establishing yourself as someone who shares good stuff, maybe you can throw in one or two articles of yours, generate some traffic and let others people learn more about your website. Furthermore, people would appreciates that you share their stuff and might follow you on Social Media platforms and if you do throw in some of your articles in the mix, people who followed you might do you a favor and share your articles or link to it.
I think what you are doing will help benefit you in the future as you are establishing your own image.
