But it's so little hassle: just send the blog author an email saying vaguely what the problem is!

Someone emailed me about an issue with my RSS feed once. I don't remember what the issue was anymore, but I was grateful and I fixed it. Being the author of a tiny blog, it was just really nice to know that someone wanted to read what I wrote enough to care that my RSS feed was borked.
