It has occured to me that [tag]RSS[/tag] (etc) readers should allow the user to [tag]refresh[/tag] the [tag]post content[/tag].
This would mean that if the post is updated, which many often are, those edits would be visible from within the feed reader.
Better: get the reader to check the posts and notify the user if the content has changed.
Even better: allow the user to set a minimum-change threshold, so that if the edit made was for example simply correcting spelling they wouldn’t be notified. But if the update was adding new information then it could trigger.
If anyone knows whether this has already been done, please lmk so I can be suitably ashamed for my complete lack of research.
