I'm getting turned off from reading some people's blogs.
A big turnoff for me is a big blob of text that does not use paragraphs.
If you do use paragraphs and decide to left justify your paragraphs, put a blank line between the paragraphs -- hit the carriage return (or your Enter key) twice instead of once. Otherwise, you just have a big blob of text which equates to bypass, go to next blog.
Here's an alternative if you're too lazy to hit the carriage return twice, indent your paragraph -- hit the tab key or the spacebar consistent number of times -- to show that you are starting a new one. Of course, it most likely would not like you doing that as HTML gets rid of extra spaces or does not understand what a tab is.
Starting a new train of thought...new paragraph. New paragraph, hit the Enter Key twice.
Easy peasy. Keep your readership.
