Blogging is fun but you can see that many of the successful bloggers write about technology. In fact, in blogging world, two things can bring good money for you:
I have experience of writing about business, entertainment, sports, literature and technology both in professional and personal blogging capacity. In the blog networks, there is always a good demand for bloggers who can blog about business or technology. The same goes for earning money online too. You can have good income from these two fields. Of course, you can good money from any topic as long as you can generate thousands of visitors.
After 11 months of professional blogging, I have realized one thing very well. If you really want to make a living from blogging then you should have a flexible attitude. You should not be selective about what topic to write. In fact, if you have some knowledge and interest about technology and business then it is really a good idea to write about them. This way, you can make a name for yourself quickly and then switch to the topic that you really love to write.
