The discussion and interest on Twitter about a recent hiring issue between Cisco and a candidate is a fascinating case study. For privacy reasons, we cannot comment on individual personnel matters or hiring decisions, but I would like to address, in general, our thoughts on social media, such as Twitter, and offer a different way to look at these great new collaborative tools. I personally think these tools are an amazing new form of expression and collaboration and as a company, we recognize the opportunity they offer and we encourage their use. It’s normal for people (and companies) to make some mistakes when they use something new and we should all learn from those mistakes. And, that’s my point: we all can learn from these tools together. They are new and very popular and not all people will know how they work or what impact they have or even who the audience may be – but we are all in this together.A common statement in the public relations world has always been “don’t say it unless you are comfortable with it being on the front page of a newspaper.” Now, with Twitter, the world is coming to understand something new: “don’t say it, unless you want it turned into a meme and hashtags and websites and videos, etc.” You obviously never know what is going to go viral, but it would be a shame if that fear kept people from communicating through these important new forums.Words are powerful and you have to be willing to stand behind those words or be ready to defend them. Maybe we all already knew this, but with Twitter and social media and new ways to communicate, maybe “re-learning” isn’t a bad thing.Please view our employee guidelines for social media and internet postings and let us know what you think. And, of course, please follow us on Twitter (@CiscoSystems). And more Cisco tweeters here.
