I have a problem adding a custom sharing button to JetPack
I've added it as follows
Service name: Hacker News
Sharing URL: http://news.ycombinator.com/submitlink?u=%post_full_url%
Icon URL: http://ycombinator.com/favicon.ico
The button appears, but the URL it point to is
http://[posturl]/?share=custom-1350037116&nb=1
Clicking on it just reloads the current page. There doesn't seem to be anything handling the ?share= - and anyway, shouldn't it just point to the sharing URL?
