Digging for new extensions

If you didn’t know Digg has extensions (pictured), but I’ve heard @kevinrose talk about community founders being able to build their own.

For /money I’d have a ‘best of last week’, ‘best of last month’ expandable summary, aggregating snippets of prior posts to catch up and link off to.

For /sidehustle I’d have a deadline extension where members can publically set a deadline on a goal orientated post for their side hustle automatically resurfacing the post in the feed on that deadline.

What would you build for your community?

Ps. @justin are user built extensions still on the cards?
