One revolutionary feature added to blogging engines was the ability for readers to post comments on blog posts. Responding to any reader response, either positive or negative, is a good way to encourage readers to maintain their interest. This reception will show that a blogger is aware of and appreciates the presence of his or her audience. This can establish a dialogue between author and reader, which can enrich subsequent blog posts. Ignoring reader comments, or responding hostilely can drive readers away. The effective blogger can spark a discussion with the audience with a blog post and continue that discussion with on-going comments.
