User interaction within a virtual space is facilitated through unintended side effects to primary interactions between users. In the virtual space, primary interactions between source and target users have unintended tangential effects. The tangential effects are provided to other users. The other users are users which are active at the time the corresponding primary interaction was triggered, and are relatively likely to enjoy participating in the virtual space with the source and/or target users. This may encourage interaction between the users as they respond to the tangential effects (e.g., by responding to the source user of a primary interaction that caused the effects).
