Tweet, Like, Google +1 and Share Plugin in wordpress is one the very simple social share plugin with just 4 social icons. With less social icons there will be lesser load on pages and it will load much faster. I have tried to use this for almost half a year now and I like the good effects on my blogs.
When you install this plugin, there is a default settings but you can change it to the way you like it to appear on your page. In the photo above, I place the script in the header, change the size of the icons to small and set to left aligned. It is loading fast and whenever I do not have new post, I just share my old blog post so that my blog readers and other readers will be updated to other post that might be helpful to them.
