I don't know about you, but I have a distinct aversion to paying for anything I can whip together myself. Don't get me wrong, I am a fan of outsourcing, but only when a particular task has been well-established and now takes away from another biz-building task that require personal attention.
I am working my way toward setting up a long-term online business. For the niche to be successful, I need a loyal following.
I started on Facebook in August, and even after taking 3 weeks off and not visiting every day, I have close to 1,000 friends and have been joined by them to groups totaling close to 200,000 members, all in a targeted market. It's a market I really enjoy, and gaining the requests and recommendations has everything to do with how and why you post. And it's all free.
There's more work to be done before I can begin gathering information for site articles that must be in place prior to publishing.
What I am saying is that you can create an enthusiastic following through social media in any market, even one you know nothing about, and in doing so, learn what your people need that you can gather in one spot and furnish for them.
