I’m learning that the hardest part about keeping a blog (aside from finding the time) is deciding what point of view to write from.
This is especially hard because I don’t have any audience.
Presumably a technical writer focuses on technology and assume his / her readers have some base level of knowledge. Business writers likewise assume some knowledge of relevant issues.
In this way, writing is a lot like marketing; you need to know your customers or you can’t give them what they want.
