Farmer suggests a domain expertise strategy as suitable for most people who are not trying to be “citizen journalists”. The idea of this strategy is that most people are really going to make their mark talking in-depth about something they know, vs. attempting to be one-person news criers coming up with something new every five minutes. People following the domain expertise strategy will post longer pieces with meat on them. Their readers will read them for the in-depth view on topics of interest. I have a couple of tactical additions:

• As I suggested in an earlier post, in the domain expert strategy you need to blog like a tadpole. You need to pack the main message up front and let the details tale off the end so that the time-pressed reader just gets it up front. If they just get it, even casual readers will then point at your article, and other readers who have more time will find you because of the search visibility gained from earlier readers' links. In grade school, we called the writing strategy “newspaper writing”. In the blog world, it has the added attraction of fostering links back to you.
• Another thing I would suggest is to break extremely long posts into multiple posts. The extremely long post suggests you are writing about multiple ideas. It's always harder for readers to understand multiple things at once. You need to weigh this cost against the benefit of the synthesis. If the main benefit is in just one of the ideas, write about it and find a way to skip the others. Again, it's an issue of making your idea accessible to the widest audience possible.
