We've just launched several new features that we've been working on for the past few weeks.
The subscriptions system has been completely rebuilt to 1) support notifications on a much broader range of events, 2) make it possible to receive all notifications by email and/or on-site notifications, 3) allow for batching of notifications.
How to Subscribe
The triple-dot, drop-down menu on posts and comments now have multiple subscription options. You can now subscribe to all posts from a given user, all comments on a given post, all replies to a particular comment, and local groups, with some more options for subscriptions coming soon.
On desktop, hovering over posts in post lists causes the triple-dot menu to appear.
What the triple-dot menu looks like
Viewing subscription options in the triple-dot drop-down menu
Subscription settings can managed in the Notifications Panel of your User Settings
You can manage individual subscriptions by accessing your subscriptions page from your user page or via www.lesswrong.com/manageSubscriptions
For your convenience we have added bookmark functionality to help keep track of those wonderful posts you might not have time for when you first encounter them. Using the triple dot menu, you can now find a bookmark option.
Viewing your bookmarks
By default, your bookmarks are displayed at the top of the home page in the Recommendations section. This can be configured via the gear icon
Clicking on "Bookmarks" will take you to your bookmarks page which lives at www.lesswrong.com/bookmarks. You can also reach your bookmarks page via the drop-down menu when you hover over your username in the top right.
Pingbacks [Experimental Opt-In Only]
When a post has been linked to by another post on LessWrong, the pingback feature will list any referencing posts at the bottom of the post page. "Pingback" is equivalent to "cited by".
This feature is currently only available to those with experimental features switched on since we are still actively iterating on it (see your account settings to opt-in to experimental features). Note that not all historically used LessWrong URL schemas currently work– this will be fixed before the general release of Pingbacks.
We hope you find these features useful!
