Comments should have their own page, like on hiveblocks.com
Comments are very specific type of operation, so they deserve their own view. Currently on some operations permlink points to the comment on hive.blog - it should instead point to page on block explorer and only there should be links to popular front-ends (preferably configurable) - just like on hiveblocks.com. All comment related operations (that contain author/permlink pairs) should have links to comment page, f.e. comment_payout_update_operation
. Replies should have links to both comment page of the reply as well as link to comment page of parent post.
