Blogging, in my view, has evolved into an art form of expressing individualism and social activism/agenda.
If it's detailed, it's already journalism.
If it's about political correctness, it's diplomacy.
However, I would like to see more understanding expressed in few sets of words/sentences. Delivering the thought or message in fewer words depicts one's wisdom.
Readers' interaction through comments depicts a dynamic blog. Diverse interaction from various readers will bring more radiance to the blog. Interaction from a usual set of readers may be viewed as eccentric (not at all cases), for a newcomer.
The longer the post, the lesser the interest. Communicate the message, not the eloquence of words.
