When analysing the chatter activity object, I see the property "post count" what does this mean? What exactly constitutes a post? I am pretty sure that the feed track posts due to a status change are not included but I would like to know exactly what is included in "post count".
I've read the documentation but find it rather vague.
PostCount
Description: The number of FeedItems made by the ParentId.
ParentId
Description:Identifier of the object type to which the ChatterActivity is related. In API version 30.0, the ParentId must be a UserId or SelfServiceUser ID.
