Twitter. What are the #'s for?

[Camille]

I guess you can call it a "trend". The number sign is called a hashtag. It's pointless and makes the person look completely stupid if used on Facebook AND if used excessively on Twitter. Hashtags are kind of like "marks" to indicate the "keyword/phrase" and what the topic the tweet is about. If you click on the word with the hash tag, you'll see more people tweeting about the topic.

A lot of people just make things up with the hash tag and that's perfectly okay. You can put hashtags pretty much on any word or phrase of your tweet, but for phrases they CantHaveAnySpacesOrPunctuation. It's up to you to decide on what word/phrase you think is the keyword. There is a column for "Trends" and you can see what is "trending", those are the most popular trends on Twitter for today. You can use those popular trends to tweet about something relevant, or just make something up on your own.
