A blog comment hosting service[1] is a service which externally hosts
comments posted by users to blog or
online newspaper posts. Many such services allow for users to log into a blog comment hosting service using
social network profile credentials such as those of
Facebook Connect,
Yahoo!,
Google,
LinkedIn,
Myspace, etc. Such services may also have an effect upon instances of
comment spam, as prior registration with comment hosts may be the only means by which to make comments onto many blogs.
