This is not a state unique to me - so many of our clients tell me the same thing - and my advice is this - when blogging, make sure that you keep up the quality of your content and use your blog when you have something really important to say. Link to it from all your social media outlets and give the reader more bang for their bucks. This is a 24 hour communication world - it's expected that someone from every company is available 7 days a week and that's tough if you're trying to balance quality of life too, but it is possible to achieve if you make use of the most appropriate medium for the job in hand.
So, you can expect to see me on Twitter, Google+, Facebook, Pinterest, Instagram, What'sApp and Skype too, but only when I have something useful to say ...
The moral of this story is, don't just bang on about nothing, make sure what you have to say is worth reading, or hold fire until you do.
