16. A system to recommend hash tags to be inserted into new comments as the new comments are being generated, the system comprising: a corpus analyzer, executed by a processor, to analyze corpus of existing comments to extract user-added hash tags along with concept information associated with the user-added hash tags; a hash tag database, executed by the processor, coupled with the corpus analyzer to store the user-added hash tags and their corresponding concept information, where the hash tag database stores information on a corpus of hash tags including hash tags having a highest reach within the social network, how recently and heavily the hash tags in the database have been used, and which concepts the hash tags in the database are associated with, a comment analyzer, executed by the processor, to: analyze a new comment as the new comment is being generated to determine concept information included in the new comment, determine if a link is included in the new comment, in response to determining that a link is included in the new comment, extract content that is referenced by the link, and determine the concept information from the extracted content; determine hash tags that are associated with the concept information from the hash tag database, and prioritize the hash tags based on how recently the hash tags have been used in other posted comments and a maximum reach and impact of adding the hash tags to the new comment; and a publisher, executed by the processor, coupled with the comment analyzer and to present the hash tags in a prioritized order to enable one of more of these hash tags to be selected.

The system of claim 16 , wherein the comment analyzer is coupled with a concept server connected to an Internet network, the concept server implemented with an Intelligent Data Operating Layer (IDOL) application to determine the concept information associated with the new comment.
