Hi Megan
Yes, when using Twitter correctly it can be very beneficial for you & your business. There's so many connections to be made using Social Media. One thing to remember, it's all about building relationships and letting others see what your about and what you have to offer, not promoting yourself. In terms of Social Media it's best to be yourself, build your following and let potential clients come to you. Not only are potential clients on Twitter, so are a multitude of others. It's a place to network with a variety of industries.
I suggest taking the time to read the blogs URL="http://www.virtualassistantforums.com/blogs/jkvirtualoffice/"]here[/URL] posted by Kimberly LeRiche [@jkvirtualoffice]. She's such a great example of how social media should be used. Also, the
Social Networking section has a ton of valuable information related to Twitter.
Hope this helps you some. If not, post back with any other questions you might have!
