With every blogger wanting to capture readers, it goes without saying that if every blogger did nothing but write on his own blog, there would be no interaction between anyone. Sometimes, bloggers are the most prolific commentors. If you want people coming to your blog to check out your ideas, you need to sally forth and announce your presence on other blogs. Find a blog that discusses the same topic you do and engage the blogger by leaving a comment. You can even leave a link to your blog in your comment. I wouldn’t do this all the time, especially if you comment on a particular blog multiple times. If you really want some fun, find a blog that discusses the opposite point of view from your blog and leave a comment and link. Now, we do want to foster communication and discussion, so name calling and similar juvenile behaviors will not foster positive interaction. So, get out there, let the internet world know you exist, and keep it civil.
