Context

The thing I like about blogging is that they lend themselves to being concise while you can also ramble on as long as you like. For instance, Andrew Sullivan's blog mostly consists of posts that are less than 300 words, but when he wants to, he can write as long a post as he likes. One reason he's so successful in the medium is that he only writes as much as is necessary to make his point. That's invaluable. I don't know how many articles and columns and papers I've read that take many more words to make a point than is necessary, simply because the form being used demands a certain amount of words.

You need a lot of space & time to make your point if you're making a complex arguement or your topic requires abundant proof, and so time and space is dedicated to your sources. Otherwise, please, we're all in more and more of a hurry. Get to the point.
