I'm basically going to reiterate what has been previously discussed about technical writing. Technical writing has the base primus to make point to speak directly to an outlined audience, about an identified topic and/or ideal, for a main objective to be reach.
The writer must identify his of her audience in there writing and must be able to connect and hold there audience's attention, by being able to speak the general language that is a commonality amongst the audience. By being able to keep the focus of the writing where it is easily understood by the audience, the writer will be sure not to undermind the intellegence of the audience for which the specific writing is being done.
