Response to Social Media News Releases:
I feel as though the idea of sending news releases to the public via social media is a solid one. It is sure more effectively received than a direct mail list or possibly even a email group. The main drawback to this form of News or Press release would be that it could be discarded as junk, which is so often the very same problem faced by direct mail packages. The idea of utilizing PR or News Releases through social media as a means to reach the public is one that is solid and has been proven to work not only through these examples but also by personal experience of the author.
