I am thinking on making a blog, though not sure about the niche... if you do have a blog, what is it? do you support news blogs? cause this is the most updated content, and you just take a news from a news site, sumrize it with a bit of words and then send a link to the news!
I blog about anything that I can think of lol If you want to start blogging choose a subject that really interests you and that way you'll be able to provide valuable information
