That's it, now I've REALLY done it. A client asked me to be his "friend" on Facebook and I declined. Yep, declined.
But there is method behind my madness. Just like in the real world you choose where and when you "meet" clients and where and when you "meet" friends, well the same is true in the online world.
I explained to my client when declining his friendship that my preferred location for online networking with clients in on LinkedIn, in fact we now run a Client Forum on LinkedIn for our clients.
So, hopefully he understood why I rejected him and hopefully he's learned something that he can use in his own social media strategy.
