(CNN) -- Say what you will about Facebook, but the social network is not too proud to copy. Facebook is reportedly considering co-opting the hashtags that first emerged on Twitter, following its previous aping of the Twitter model of following strangers and sharing content publicly. Facebook is testing the idea of supporting the use of hashtags in posts to the social network, according to reports in The Wall Street Journal and other publications. Facebook has declined to comment on the reports. Hashtags, unique and often cryptic terms preceded by a hash mark ("#"), are specially tracked and aggregated on Twitter as they would presumably be on Facebook. Twitter shows which tags are trending, and clicking on a hashtag brings up other posts with the same tag.
