There's a long standing request to get some generalised values for a URL from the API.
- Number of +1s
- List of people who've +1ed
- Number of reshares
- List of reshares
- List of resharers
eg https://code.google.com/p/google-plus-platform/issues/detail?id=57
https://code.google.com/p/google-plus-platform/issues/detail?id=621

For some reason I thought some of this was available via badges and buttons but although I can find the share button, https://developers.google.com/+/web/share/ it doesn't seem to provide the share count or provide a link to Ripples.

I feel like all of this should have some UI and an API but several parts of it seem to be missing.
