Yes. If you look at modern blog networks like Latest Blog Posts at http://www.latestblogposts.com, you can see people blogging constantly. I actually maintain 3 blogs of my own and I find that it brings more traffic to my site than Google search results.

Fashion blogs are very popular, because fashion is always changing. A fashion blog that keeps up to date should do very well and also bring in income from affiliate sales.

Blogging is only as good as the quality and quantity of the blogger. The more quality blogs you put out there, the better chances you have of getting more traffic and making more money.

I hope this helps. I develop blogs for my clients. That is one of my specialties.
