I am a blogger myself, but I also like to visit other blogs. I like to visit such sites because I always have some opportunity to contribute to the discussion. This can be done by leaving a comment to a blog post. When I think that I have something interesting to say, then I usually make sure that other people know about it. I am not going to leave a comment on all blog posts, but if some topic interests me, then there is a chance that I am going to have something to add to the discussion. Feel free to leave comments on my posts as that can lead to interesting discussions.
