I have a twitter account and facebook account that I use for social purposes. I never thought of the classroom application. It is important for educators to understand social networking because it is such a big part of students lives. It is a great way to connect with the students. It is important to know what they are talking about when they reference social networking. This is also a great way for educators to connect about specific topics.
I never thought of all the different hashtag combinations that could be searched. After searching the educational hashtags I found an abundance of information. The disadvantage of hastags is that anyone can post to them and there is a lot of spam out there. Spam posts can be frustrating.
