The basic purpose of any writing/typing is to accurately and succinctly communicate information that is clearly understood by the recipient(s). For some types of writing, maybe being succinct is not as high a focus (such in novel and other writing), and you can have double meanings to play on words.
But, the basic premise is to be accurate and understood.
Good, quality writing is a skill that is underappreciated and very much lacking across all media. Here’s an example from today on the front page of Yahoo!
Taken a glance — which is what we often do on pages: glance or scan — it sounds like that Bobby Brown is not buying cocaine with money, but getting it in exchange for community service. He gives his time to help the community, and gets some drugs in return.
Ain’t that nice! 
Of course, even though we know what it reads, we likely really know what it means.
Is it just me being picky?
I hope not.
Simply, say what you mean and ensure that what you say and type communicates what you really mean.
