I have previously introduced a plugin that adds Bit.ly link shortening capabilities to the Known sharing tool.
I just wanted to post a quick update to note that I have now added full OAuth2 support to the plugin.
Previously, integration was provided by the Generic Access Token, which meant that you could only have one Bit.ly account associated with an install. With OAuth2, each user on a given Known site will be able to link to their own bit.ly accounts (with their own vanity urls if they wish).
Pretty neat!
