Thanks for your post. I am following you now so I can see all your future posts as well. I will admit I use a lot of the tags (I would suppose they are called mainstream ones) that show up on the right side of the page when looking at any new section. I don't know how helpful that is to me or not. I write a mostly about a niche topic and I feel that instead of using the first tag to put me in the genre I am in (my niche genre) I instead use the wider (more mainstream) tag which helps me to be seen a bit more. I am sure there is a better way to do it to get more exposure, would love to see what other suggestions you have for that.
