Engadget introduces "Follow the Saga" feature. Your blog should do the same.

I think this kind of feature is missing on many blogs that have some notion of "coherent content". We've all seen a link to a multi-part series on some blog with no obvious link to the first or next part.

I have no relationship with Engadget, but I think this is a useful blog feature, and more blogs should have the notion of a "saga" or "story" or "series" with its own metadata (introduction, overall tags, etc.). By tagging a blog post as part of one or more "sagas", it automatically gains inter-saga navigation, etc.
