I follow quite a few blogs in my trusty Google reader. Sometimes I feel overwhelmed by the number of posts that come through during the day. Luckily, I can star them and come back to them... anyway, the point is - I follow a few blogs where the writer is a full-time blogger. She makes money by blogging. And has many, many followers (hundreds of thousands in some cases!). And it appears that these professional bloggers get some sweet perks out of the deal - free stuff, amazing products to give away... as long as she promotes it on said blog that has 10s of thousands if not 100s of thousands of readers/followers.
* I have a problem sticking with a specific theme or point of view. My thoughts are pretty random based on what I'm reading or doing at the time that I'm blogging. many of these blogs are centered around themes: photography, cooking, gift giving, baking, minimalism, crafting, etc. Can't seem to focus my energy or passion enough on one specific topic to make it a "theme" for my blog... which means there is no specified target audience.
