Twitter share

This is a great , light and fast plugin. As I shared articles (ex below)and tried a few others before this, I wondered why some sharing on (twitter eg,) includes some extra info on sharing relative to my blog site that this plugin excludes… (via @rawassertions.com) and is there a reason for this?? Thanks
