Multiple social streams

A system comprising:

• one or more processors;
• and
• a machine-readable medium comprising instructions stored therein, which when executed by the processors, cause the processors to perform operations comprising:
• identifying a first user viewing a first set of posts at a social networking service, the first set of posts including one or more posts selected from a plurality of posts available for display to the first user that meet a first selection criterion;
• determining that a level of engagement of the first user with respect to the first set of posts is below a predetermined level based on one or more engagement criteria;
• generating a second set of posts, the second set of posts including one or more posts of the plurality of posts not previously seen by the first user;
• and
• providing the second set of posts for display to the first user in response to determining that the level of engagement of the first user with respect to the first set of posts is below a predetermined level,
• wherein generating the second set of posts comprises:
• identifying a plurality of posts not previously seen by the first user;
• and
• selecting the one or more posts of the second set of posts from the plurality of posts,
• wherein selecting the second set of posts comprises:
• determining a quality score for each of the one or more posts of the second posts;
• and
• determining that the quality score of each of the one or more posts meets a second selection criterion.

A machine-implemented method, comprising:

• identifying a first user viewing a first set of posts at a social networking service, the first set of posts including one or more posts of a plurality of posts available for display to the first user that meet a first selection criterion;
• determining that a level of engagement of the first user with respect to the first set of posts at the social networking service is below a predetermined level;
• generating a second set of posts in response to determining that the level of engagement of the first user at the social networking service is below a predetermined level, the second set of posts including one or more posts not previously seen by the first user;
• and
• providing the second set of posts for display to the first user, wherein the one or more posts of the second set of posts are selected from other posts of the plurality of posts that do not meet the first selection criterion,
• wherein the one or more posts of the second set of posts meet a second selection criterion, and
• wherein the first selection criterion comprises a first quality threshold and the second selection criterion includes a second quality threshold and wherein the second quality threshold is lower than the first quality threshold.
