Digiday.com, there are 400 million tweets per day and 200 million monthly active Twitter users. That's a lot of tweets!
Tips when using Twitter:
Hashtags are the use of the # symbol with a keyword to help categorize your tweet. It also allows others to easily search for tweets of similar interest. Hashtags first became popular in Social Media through Twitter. Now, hashtags are also used in other Social Media websites such as Pinterest and Google+. Even Facebook is considering allowing the use of hashtags.
Who to Follow
Remember, there are 200 million monthly active users, so I'm not going to give you a list of who to follow here. The best suggestion I can give you is to check out who I'm following on Twitter, @EdTechnocation, and follow them yourself. In my professional Twitter account, I'm already following 409 users who all have some kind of interest in education and technology. Visit my Twitter profile and click on the "Following" link. You may also want to check out who my "Followers" are.
Twitter chats utilize a hashtag and focus on a particular education related topic. There are many different Twitter chats that take place on a weekly basis. You can participate in a Twitter chat as its happening live by using it's hashtag in your tweets or you can search the hashtag at a later time to see how the chat went.

A Twitter Tool like TweetDeck makes it easier to follow along during Twitter Chats. In TweetDeck, you create a column that will only show tweets that are using a specific hashtag.
Don't forget, if you want your PLN to grow on Twitter, you can't just be a consumer. You won't gain any followers that way. Contribute and participate!
