Corporate release cycles... In large corporations, you rarely get access to the production environment and everything is managed by different departments. At my current client, we can only go to production a few times a year (except for hotfixes, but they need to be approved by a special board).
Luckily, our deployments are automated and we deploy to our testing environment multiple times a week, sometimes multiple times per day. That at least enables us to get feedback from the test team, which results in tickets either being moved to 'really done' or moving them back to 'in progress'. It's not the same as shipping, but in such an environment it at least reminds you of the important fact that things are indeed still moving and getting done.
Other than that i use MiniHack on iOS (https://itunes.apple.com/be/app/minihack-for-hacker-news/id6...)... I rarely use the website
