I also have had great success with SNAP, sharing to Facebook, Twitter, G+, Tumblr, Pinterest & LinkedIn all at once with no problems and minimal daily interface. Very configurable where you can set defaults for each site, then tweak settings for each post if desired. Includes shortcodes to add in title, excerpt announce (in which you preset the number of characters to share) before you add in your own “…click %URL% to read more.” so your fans must go to your website for your content, then engage with the rest of your offerings. Also includes shortcode if short URL is desired (%SURL%).
To avoid being mislead like I was by Regal H’s comment above, this plug-in cannot enable the user to follow the blogger’s instagram account or share a post from the blog to the user’s account. It only opens another browser page where the blogger’s instagram page is displayed.
