Abstract: An example social media messaging system may include a capability for a user to edit messages after the messages have been posted to the messaging system. The capability is implemented in a manner that preserves the immutability of messages that are posted to the messaging system.

Abstract: A computing device can receive at least a first post in association with a first account, a second post in association with the first account, the second post being associated with the first post, a third post in association with a second account, the third post being associated with the first post, a fourth post in association with the second account, the fourth post being associated with the first post, and a fifth post in association with a third account, the fifth post being associated with the first post, determine that the first account and the second account are most relevant to a conversation, and based on determining that the first account and the second account are most relevant to the conversation, present the first post, the second post, the third post, and the fourth post without presenting the fifth post.

Abstract: A computing device can receive at least a first post in association with a first account, a second post in association with the first account, the second post being associated with the first post, a third post in association with a second account, the third post being associated with the first post, a fourth post in association with the second account, the fourth post being associated with the first post, and a fifth post in association with a third account, the fifth post being associated with the first post, determine that the first account and the second account are most relevant to a conversation, and based on determining that the first account and the second account are most relevant to the conversation, present the first post, the second post, the third post, and the fourth post without presenting the fifth post.

Abstract: A method can include presenting a feed, the feed including at least a first post, a second post, and a third post; receiving a selection gesture in an area corresponding to the first post; in response to receiving the selection gesture, expanding a size of the first post from an original size to an expanded size; receiving a scrolling gesture; and in response to receiving the scrolling gesture, moving the first post, the second post, and the third post in a same direction as the scrolling gesture while maintaining the expanded size of the first post.

Abstract: Example systems and methods are described for implementing a swipe-to-like feature. In an example implementation, a list of content items is displayed on a touchscreen display, and based on detecting input of a first gesture, such as, for example, a swipe gesture, for a first one of the content items in the list, associating a predetermined first sentiment with the first content item.

Abstract: A computing device can receive at least a first post in association with a first account, a second post in association with the first account, the second post being associated with the first post, a third post in association with a second account, the third post being associated with the first post, a fourth post in association with the second account, the fourth post being associated with the first post, and a fifth post in association with a third account, the fifth post being associated with the first post, determine that the first account and the second account are most relevant to a conversation, and based on determining that the first account and the second account are most relevant to the conversation, present the first post, the second post, the third post, and the fourth post without presenting the fifth post.
