I decided to start posting regularly on LinkedIn, even though I'm not sure it's where my ideal clients are.
Why?
1) because it helps me in my own process
2) because there are a lot of marketing professionals on LinkedIn. If they know my stuff, it might be easier to work with one of em if I decide to.
Sure, I secretly hope it will lead to sales too.
What about the magazine you were working on? The LinkedIn stuff will be repurposed for the magazine (reasons 1 and 2).
