I don't know what suitable blog length is.
I keep trying to bridge this gap between writing essays and making posts.
When I wrote in my own livejournal, I had the same prolix problem. I would write beautiful entries, but they'd reach a length when I would sometimes wonder if people made it through to the end. As a friend of mine once said, "you write really well, but I never read them all to the end," and added a little laugh. However, I don't know how to divvy up my thoughts in a way which is any more brief. I don't want to condense myself so much that I lose an important logical step in my thinking.
I wonder about the quality of my posts as well. Twilight is so intensely vapid. Once I get over how shapeless Bella and Edward are, I imagine I can emerge into a new area. Once I begun discussing how they interact, and the impressions that a critical-thinking reader might derive from the text, I might revive what I feel has been dampened. I hope I am keeping in tune with my mission statement to deliver intelligent reasons against the book and not fiery complaints. Complaints are impotent, clever argument is beyond powerful.
Pictures present a problem, because I normally never use pictures in my writing. I know visuals would be an asset to my longer posts... but how much of one?
