A method, system, and computer program product for conforming text posted on a social networking Web site for posting on another social networking Web site. The method includes receiving text input by a user for posting on a first social networking Web site. The text is analyzed to identify topical and semantic attributes of the text that are extracted with natural language processing and semantic analysis, and then compared to a historical semantic communication style between the user and the intended recipients on one or more other target social networking Web sites. The text is then converted to have topical and semantic attributes for posting on the target social networking Web sites as appropriate for the user, recipient users and user groups, and the target Web sites.
