Digg Digg is no longer supported by Buffer
After acquiring the Digg Digg Wordpress Plugin back in 2012, we made quite a few improvements and fixed some critical bugs. Since then, with Buffer still being quite a small team, we have sadly struggled to find resources to continue developing Digg Digg. Buffer is therefore no longer supporting the Digg Digg plugin, though we have taken some steps to ensure it can still be improved by other developers.
We have completely open-sourced Digg Digg and made it very easy to find, browse the code and submit pull-requests on GitHub. You can find it here.
And as with most open source projects, there is a small community with a forum here, who may be a good resource in offering help.
We are so sorry if this causes any disappointment and if you have any questions at all, please don't hesitate to get in touch.
