CoolCatTeacher shares a post about how and why to comment on blogs that I think is a must read for every fledgling blog reader and author.
Commenting has truly been the fuel that has fired readership for my
blog and opportunity for me. It is also part of being a responsible
blogger in general.
If one is an expert, I guess they may just want to keep their "wisdom" on their own blog, but the true conversation participants are those who contribute to the discussion wherever the blog posting is.
Whether you consider yourside a newbie or an experienced blogger, I think you’ll definitely find at least one pearl of wisdom.
