Facebook Adopts Hashtags

Facebook announced that it is rolling out hashtags on its social network, in an effort to play a greater role in real-time public conversations dominated by rival Twitter Inc.

Beginning Wednesday, the company said that words in posts that are marked by "#" will be grouped together. Users can track conversations by searching for these hashtags, or clicking on a hashtag in a post. That action will pull up a list of posts the include the hashtag, with most relevant posts first, such as those by your friends, followed by most recent, publicly-available posts.
