Blogging has become increasingly popular in recent years.
There are bloggers who earn ridiculous amounts of money simply by hosting their own blogs. For instance, Michael Arrington, a very famous technology blogger, earns between $500,000 and $800,000 every month. Arrington is the highest paid blogger in the world, but there are many other bloggers who manage to live a luxurious lifestyle, simply by blogging.
You can cover a range of topics on your blog, but generally, it is better to choose a niche and stick with it, such as fashion, technology, lifestyle, etc. If you blog about everything from tech to dating advice, you will probably be less successful since the audiences rarely cross over. It is advised to stick to something you are familiar with, meaning if you are a technophobe fashionista, then stick to blogging about this year's autumn trends rather than the latest iPhone.
The way people earn money through their own blogs is by selling advertising, sponsorships and earning commissions as an affiliate. So if you are a good writer then maybe it is time to consider starting a blog. Who knows, if you are good then you might end up being the next Michael Arrington.
