Technologies are generally described for a social networking service (SNS). In some examples, a method performed under control of a server may include receiving a user input associated with the user responding to content posted in an online forum, determining whether a threshold condition set by the user is satisfied for the user's response to be disclosed with regard to a particular piece of content posted in the online forum, and disclosing the user's response to the particular piece of content posted in the online forum when the threshold condition is determined to be satisfied.
