What does the hashtag mean on facebook?

Actually there is no built-in function for hashtags on Facebook, people are mostly using them out of habit. Hashtags came from Twitter where the community decided to use them to group similar tweets together, and Twitter embraced this usage and built in a way for people to do searching on hashtags to find tweets, in other words, do key word searches. Facebook has yet to embrace this, but perhaps if people continue using them it will become a built-in function just like on Twitter.
