Share and give your opinions in your blog but don't be judgemental.
Blogging is as much about bold ideas as it is about creative expressions, Work on your language and dive into ideas fearlessly.
Formatting - Your post need not be a circus. If you are not good with formatting, then stick to a theme that is light and descent in colors and the post layout. If you are good with trying new stuff then use that skill to better express through colors, fonts and layouts. Avoid colors that are dark and fonts that are overtly bright.
