When is a blog not a blog?

What do you call a collection of dated postings, written by a single person, which expresses opinions, informs readers, and offers insightful advice. Many might call it a blog. There's one such site which I visit almost daily, yet for some reason, I access it via a dedicated link on my desktop. It's called Joel on Software. Why it hasn't been included in my list of blogs is, frankly, beyond me. Today, it gets added to my list of good sites to visit. Is it a blog? You decide. Is it interesting? For the right audience, definitely!
