Today i was reading a blog on how to fuel your bloggeing and i leaned some info about learning to keep peoples attention and i think i have got most of it down. i have videos ,good pictures,question polls ,etc.
I would recommend looking at this blog (the link is at the bottom) if your looking to improve your blog and get more page views and comments. he my say to put different kinds of things on your blog such as pottery but that stuff is boring. so take a look and maby improve your blog.
