I mostly agree. The only time you should link to past peices is if it's part of a series or that previous peice includes lengthy, relevant info. In short, as reference or citation.
As for embedding, the only time I use it is to showcase a group of reads as a round-up from a publication - certainly not within my *own* stories. I do like how some editors provide weekly lists of top stories from their publication. But I also know what to expect, and it's not a regular story.
