It is often recommended by (Pro) bloggers that connecting emotionally with your readers is a good habit. But, it is not recommended that you connect so much that you “lose it” or be too opinionated in a blog. This is because it makes it less business oriented. So, you should strictly draw a line as to where you should stop being emotional. Moreover, too much ranting emotionally about a topic makes you look like a distressed sixteen-year-old girl writing in her diary. An emotional outburst in writing can clear an online room just as fast as displaying immature or raging behavior can in real life. People just don’t tend to trust opinion that is attached to a libidinous display of emotion.
In fact, unless you are a great columnist or a humorist, your blog should never take the form of a rant, and it is strictly not recommended for a business blog. The structures of these types of blogs are generally therapy to other readers. It goes better in a personal blog, if you want to or froth at the mouth about your favorite controversies. Don’t take me wrong as I don’t intend to mean anything bad about a personal blog. What I’m trying to say here is that ranting too much in a business blog is not desirable and it can never be a good business marketing strategy.
Rants can also be made to work in certain cases to a certain extent if they are liberally sprinkled with proper and effective keywords. A good way to write a successful rant on a business blog like this is to sift through latest news articles and informational products about your theme and then to write your opinion / insights to the news. Again crafting these kinds of articles is a real pain because people looking for information get bored off easily with the flow of too much emotion in the article.
In certain cases it is often found that if you are too much emotional on your blog, it discourages other to respond to you. Naturally they will not find the spirit to leave a comment or a pingback if you attack them personally. Just imagine keeping yourself in the same position and think how you would react to a rant and how much negativity would generate in you. It might also create an impression that their comments might be removed if they oppose your views.

“Dear diary, today I am totally upset because I am not able to make money online”
If being serious, it is ok to share some personal details or emotions as long as others can get some type of lesson or knowledge from it, if it is just you crying over spilled mild – don’t share it on your business blog.
Ups and downs are in every ones life so while blogging readers want to take a break and refresh their mood. I think that could be the reason for ignoring ranting blogs.
