It's not been asked as a broad question here yet, but we've all wondered: how does one go adding comments to a Craft site, such as those you'd find on a blog?
I've either used or been aware of...
- Integrating Google+ comments.
- Using a dedicated Craft Section for comments and relating each to a post, collecting submissions with Guest Entries.
Are there others out there? Would an expert comment engineer care to answer authoritatively?
