Twitter’s share buttons used to have a share counter in them. , Twitter changed the look of their buttons and removed the share count along with the unofficial and undocumented API endpoint that powered it. Many third-party tweet buttons that used to display share counts stopped working.
In a blog post Twitter suggests that people who still want to know the number of shares for their articles should use the Twitter’s REST API to obtain the share counts by counting the results. For many users this is not feasible because of the technical complexity involved.
OpenShareCount aims to make this process a little simpler by providing a drop-in replacement for the old, undocumented and unofficial API endpoint that all the existing official and non-official share buttons were using. For people using Twitter's default button, OpenShareCount provides a bubble with a counter to place next to it.
