One piece of functionality I thought was oddly unincluded in SharePoint 2010 was the ability to create comment trails for content types other than blog posts and to a lesser extent discussion boards.
I'm working on a SharePoint server where several custom content types built could benefit from comment trails. So far online I've only found semi-solutions to this problem. I've found solutions that allow a user to post a comment once (which is why I keep using the phrase comment trail, so that people can respond back to each other) and a solution that creates an associated list that tracks the content type's ID and does commenting that way.
While I'm not knocking those solutions, they really aren't scalable (I'd have to create several associated lists) nor do I think they'd work well with search.
Has anyone come across a solution that adds commenting to non-OOB content types with comments? Paid or free -- I would just like to see if anyone has found a better way to do this than my current best answer of creating several associated lists.
Thanks in advance.
