After closing blog comment system, some rituals may changing. Usually, common users may always open their mailbox or blog’s dashboard to check whether any new comment coming. Sometimes releasing them from the antispam trap is needed. Then, answering some questions or replying on-topic comments. Most argued that they should giving responses to any comments for the nice relationship.
With no comment form anymore, there are no rituals like that. Blog writing is on the go.
In my opinion, blog-related comments are still important (Dani Iswara .com). I have a lot of posts talking about blog comment system.
