This tip applies to your blog website.  Please add some form of share button to your blog.  You want your readers to be able to share your post easily on Twitter, Facebook, Delicious, and the list goes on!  By adding a Share This or Re-Tweet button to your blog, you do your readers and yourself a great service!  You save them time, while also allowing your information to spread faster.  If you want your content to spread, make it easy!  There are various plugins for WordPress that will add a way to share posts to your blog (I use Sociable).  Or just Google “share button” and you will find many options.  You are working hard to provide great content, now make it easy  for readers to share it.
