Most of us used the social media tools like Facebook and Twitter just for our personal social life, we feel much more comfortable leaving our working issues out of the personal life.
For this reason, a number of other sites such as LinkedIn were used for professional businesses. This is due to higher privacy that this website offer. Over time peoples become much more confident to build their professional profiles on these sites rather than on Facebook.
This scene might change in coming month as news cited that Facebook is currently building Facebook At Work to challenge the status quo.This latest move by Facebook might become a threat to the sites that offer services related to finding jobs and build work-related network.
Soon enough we may not see Facebook just as a social media, but rather as a new social working media.
