Building an audience is hard work.
There are no shortcuts for getting in shape. It takes motivation, consistency, and lots of hard work. Fortunately if you put enough work into it you see results. This leads to momentum, and once you have it things get a little easier. I think this idea can also be applied to building an audience for your blog, company, product, or whatever.
I'll probably have more to say about this later. In the meantime I would love to hear stories from people who have put effort towards building an audience (with good or bad results).
