Do you invest time in blogging?
Do you have a blog? Do you outsource it? Do you think it's important to have a blog?
I don't invest time personally but I do believe it's important to have mediums through which you communicate with your target customers or whoever it may be you want to reach.. whether that be through blogging, video, email or social media.. media that you own.
To nurture existing and potential customers, it's important to have dialogue that connects you with them; a dialogue that you can control (as compared to PR/media).
