I recently started using Tamari over whatever the standard US form of soy sauce is. The difference was something of a revelation. The depth and complexity of flavor is an order of magnitude more interesting than what I had been throwing around in the kitchen. Marinating some shrimp in it for 20 minutes was incredible. I'm wondering if there's more that I'm missing.
Wikipedia has a load of info on Soy Sauce varieties, but it doesn't really answer the question of what they taste like or if there are certain uses they lend themselves to.
I have 8+ types of vinegar in my kitchen. Is soy sauce a similar exploration? What are the common types of soy sauce? What is the difference in flavor profile? Is the usage different? Have I discovered a new kitchen addiction to drive my wife nuts?

This is a complex question, because there are several different ways to categorize soy sauces:
To muddy the waters further, add into the mix the fact that flavor is most deeply influenced by the proportion of soybeans to grains -- yet this crucial factor is not typically used directly as a categorization tool.
To focus my research, I tried to find a site that felt as though the writer was speaking directly to you: one that would encourage, and not overwhelm or confuse, as you decide whether to become a soy sauce affectionado. Specifically, I wanted a resource that clearly addressed FLAVOR PROFILE and USAGE. Surprisingly, a blogger named Barbara came to rest as my #1 recommendation: Tigers and Strawberries. I like the simplicity and clarity of her writing style, as well as her experiential platform (complete with honest explanation of her biases). The endless comments after her post provide additional insights that might be helpful, as well.
Of course, Harold McGee always provides wonderful more scientifically-based, yet still somehow understandable, explanations. He takes 5 full pages (496-500) in his book On Food and Cooking to discuss soy sauce in all its layered glory.
