Sound Bite Blogging

For those people who blog daily or semi daily is there an optimal post length that keeps people reading regularly without feeling overwhelmed?

I fully admit to being a member of the short attention span generation. My life is busy enough I don’t need long introductions, set ups, or window dressing, just give me the goods and let me move on. I can’t tell you the number of times I’ve watched a YouTube video and yelled to myself or out loud “get on with it already!”.

With the exception of the “search industry” most blog posts I come across are in the 200-300 word range. I’m sure this is in part due to contractual obligation, but are people only reading “sound bite” style posts because that’s what they’ve been conditioned to read or does there attention drop off on regular long posts?

From my own experience I skim the titles of all posts if it doesn’t catch my interest in subject or by author I breeze over it. If I open it and it’s too long I “star” it for later. One could argue that with help you build a Digg culture and get you those sought after links. You authority problem would be short lived once you built up critical user mass.

So for those of you who run multiple blogs, what other advantages are their to “sound bite blogging”?
