Once this limit was reached, rather than dropping the oldest blog posts from the feed file, they just stopped adding the new ones. I've addressed this by limiting the feed file to only the newest 10 posts, so there shouldn't be a problem in the future, but in the meantime those subscribing to my blog have missed the last two posts.
I encourage you to still read them, especially, "What we do to our kids: 19% and it can never be discharged in bankruptcy". This is a very important issue that's little known and discussed. The other post, "It's far better for China to increase demand and net-imports through investment spending than consumption spending", is on a far larger and more covered issue, but I think it contributes some important points that are widely misunderstood, and is well explained.
