A blog is a conversation. People go to blogs to read AND write, not just consume. While Yahoo allows reader comments on their official blogs some prominent blogs like Google Blog and Seth Godin do not allow comments. According to Wikipedia ‘the ability for readers to leave comments in an interactive format is an important part of many blogs.’
In Techcrunch Michael Arrington raises the question if the definitions of ‘blog’ should be revised to exclude journals that do not allow reader comments?
The current definitions of ‘blog’ in most dictionaries don’t mention reader comments at all when defining the term.
