CoComment, the new service which provides a unified place to collect a feed of your blog comments through a bookmarklet which ‘co-comments’ your conversations, have finally added retrospective commenting. This is perfect for users like me who don’t have a home terminal, and frequently can’t install bookmarklets. The feature allows users to go back and retrospectively tag comments they could catch at the time of posting, and will hopefully make it a lot easier, and more worthwhile, to comment on blog postings from now on.
