The community ads aren't showing on the main page. It's taken a couple days and multiple people to be sure (per Chernoff I have resisted the urge to sit on my F5 key). Please fix them (again)!
I have worked with Chernoff a few times on getting these ads fixed :) I just pulled a report for the impressions served over the last week- the open source ads served over 3000 impressions, so they're not broken, they just have a low Share of Voice (SOV). I will increase the SOV and ask that you keep me posted.
