A really easy way to make it easier for people to share your articles, photos, posts, etc. is to use AddThis on your website.
From their website:
AddThis helps you integrate sharing tools into your site, spread your content, and drive social traffic. In-depth analytics provide insight into your audience and their activity.
The buttons will allow your visitors to post to Facebook, Twitter, Google Plus, Reddit, StumbleUpon & more.
The analytics are also VERY useful.
