Blogging is a pastime / distraction for millions of people around the world. Some blogs are little more than a dry account of someone's day but some are really in-depth tomes about tough issues and can be a really enriching read. Depending on what you like to read and what kind of writing you like the most, different blogs can be an instant turn-off or instill a great affinity for them. It is important, however, to ensure that you blog about things that are true to you and
what you feel is important. People of the same mind will find your blog and engage with what you have put forward.
Clear-cut
When you write, you should write about something that is a very important subject to you. A subject area in which you have great skill or expertise. That way, you're contributing your wealth of knowledge to the internet and when people in need find it, you'll have helped them immensely. By blogging about a few key themes, you can also ensure that you have a focus to your blog and people will come back again and again for that. The reason is, to get the same high quality information in an area that interests them. This adds strength to your blog and makes it a powerful social tool as people may take your advice / experience into their decision making when they see that you're a bit of a guru on the matter.
Opportunity knocks
It may seem strange but by blogging, you are demonstrating the skills you have as a perceptive writer who chronicles life and issues in the real world. This can be an attractive proscpect for employers. Remember, employers read blogs too as they're only human and if they spot that pizzazz in your blog. This demonstration of skills is much better than any interview as it shows the employer directly that you're able to see things and write them down in the way that many people can't. You never know, you may get a job offer in the (e)mail.
Support
As I said above, blogging is an excellent way to put down your opinions and advice for the benefit of others and this works well in many cases. It's also a good way to let of some steam about a trouble in your life. By blogging, you can start a focus group on a specific issue and discuss problems that people have in life then move toward a solution. The anonymity of the internet can give people solace as they can get support in this way when they feel they are at their most vulnerable. This is a more social application of the blog. However, the opportunities afforded by potential job offers resulting from your writings should also be borne in mind.
Remember, blogging can be fun, a crutch in times of emotional hardship and a route to a new life through the potential to get a job from it. Above all though, be true to yourself and write what you feel is important and the world should know.
