A method, system and computer program product for providing contextual relevance of an unposted message to an activity stream after a period of time elapses. A comparison is made between the current state of the activity stream at a second point in time with respect to the state of the activity stream at a first point in time, which includes an unposted message. The relevance of the unposted message with respect to a current topic of interest in the activity stream at the second point in time is quantified. If the contextual relevance of the unposted message with respect to the current topic of interest in the activity stream at the second point in time is less than a threshold, then the user is presented with an indication of the contextual relevance of the unposted message to the activity stream.
