I often give aspiring bloggers this key piece of advice: if you're starting a blog, don't expect anyone to read it for six months. If you do, I can guarantee you will be sorely disappointed. However, if you can stick to a posting schedule and produce one or two quality posts every week for an entire calendar year... then, and only then, can you expect to see a trickle of readership.
