Deciding what really fits in an encyclopedia isn't simple. Wikipedia has spent literally a decade working out a set of rules that balances utility, fairness, quality, and maintainability. Those rules will inevitably seem bureaucratic and opaque to people who haven't worked on a number of articles and then really considered the problem.
Deletion discussions are perennial magnets for non-participants who believe that they or their (friend|band|ancestor|website) belong in Wikipedia. They are inevitably upset. Worse, in Pauli's phrase, they aren't even wrong: they start with the premise the article should be kept and then say whatever they think will let them win.
In this case, the bloggy ranter doesn't get basic Wikipedia fundamentals. E.g. that Wikipedia isn't about what's true, it's about what's verifiable[1]. Suppose he thinks that his pal is the most important person ever. He might be right, but what matters is what can be proven from reliable sources[2].
Making deletion review more approachable to the personally outraged would certainly increase the number of reviews, but it wouldn't materially change the number of articles kept. What it would do is waste a lot of valuable editor and admin time.
