I had a problem with my blog. A post I had published disappeared, and an old post was emailed to subscribers. Apologies to subscribers about receiving the old post; hopefully it did not hurt to be reminded that paying down high-interest debt is a good investment.
Although more than half of the post I had written had disappeared from the draft version, a kind member of the Google Blogger forum informed me that the blog post was "cached", and provided a link to the cached version, so I was able to retrieve the full post, and did not have to rewrite it. It has since been posted (Vanguard LifeStrategy Funds).
