Social media I use

Three social media I use are
1. Twitter
2. Social network sites- such as facebook, but you should not be able to see it.
3. Blogs

I think that choosing which social media tool to use is mostly dependent on what you are trying to accomplish with your post. Are you trying to share a short or long message? Is it more important to reach the largest possible audience or a specific audience? A small, more active audience can sometimes generate more change than a loosely connected group.
The limit on twitter makes it ineffective for mostly everything. News organizations that use it must learn a new way to attract attention to article links that often obscure the truth. It is good for established organizations as an alternative means of sharing links and sharing photos.
Facebook is a constant stream like twitter. You can not guarantee that your content is at the top of peoples pages without paying. This social media outlet is where most people spend the most time. In 2012 56% of Americans had social media accounts and I am sure the number has only risen since then (Fox, 2012). An example of a successful page for a company is Old Spice. It is not easy to link social media 'likes' with increasing profit. The most effective way to grow your audience on facebook is with humor and cuteness. If your brand lacks this then you have to consider how to create it and possibly give up some seriousness. Because of its size, facebook is best for reaching a wide audience. 
 Blogs are an excellent way to share longer articles.  However, I would not consider them an effective way to market content. Generally you share links to a blog through a different social media site in order to generate clicks to the blog. Blogs are normally shared via an RSS feed or web feeders. It is not an easily accessible thing to find a new blog unless you find the link through a different social media source. New bloggers have to establish an audience. They may share it with friends and have to establish trust before growing. Blogs are best for sharing detailed information with a deeply entrenched audience.  I am excluding "blogs" on news sites because they are more like columns.
