I was interviewed by Belle Cooper for the Zapier blog about Unmark — our open source bookmarking application:
But, we decided to make it open source because we didn‘t want it to become like every other service we loved that ended up disappearing. If we built it in the open, it can live on forever for anyone that wants to use it.
Unmark is #8 on the list. A lot of great applications are mentioned in the post.
