Listed alphabetically. Tag text size denotes popularity. #Hashtag is used in community stream and group posts by adding the # symbol directly in front of text or a text string without spaces. When you click on a hashtag from the community stream or a group you will be directed to a page with all posts containing that hashtag. Tagged posts will be sorted chronologically with latest at the top just like all stream posts. Hashtags can help index keywords or topics and drive content from the Trending Hashtags widget. Only members can view hash-tagged posts. They can work great for helping you categorize, drive and organize your posts locally by hash-tagging with city names for example. Hashtags displayed in larger font above or more popular meaning used more which indicates “trending”.
