I would recommend you copyright and licensing your code under your business name.
The question you are asking isn't about linking to your real name, it's about providing the legal niceties a business structure offers. And yes, it matters for little projects as well as big projects.
Even though it was ridiculously easy to link through to what you claim is your real name, you should still consider using a business name. I say "claim" because nobody knows if you're a dog or not. Personally, I'm just a very sharp border collie.
All of the situations assume that you see continued success, and perhaps even astronomical success with selling your software.
- When you bring other developers on board, it's easier to have them assign copyright to a business entity. Likewise, if they are given joint ownership in the firm, assigning the assets (copyright and licensing claims) to a business entity allows things to be dividable.
- How about when you decide to venture off to something else and want to sell off the assets you have delivered? Instead of having to piecemeal everything, you can sell the business itself. It's a much simpler transaction.
- Think of yourself as building a brand right now. If you decide to pursue other lines of business, you can generate another brand at that point. Then you don't have to worry about consumer confusion created by having disjoint products under the same brand.
- Once you incorporate your business (see additional details below), then you acquire legal protections and additional financial / tax options to consider that may benefit you.
There are the additional psycho-somatic nuances of a business name versus a single person, but the links you provided go into those details.
On the flip side, if things are an abysmal failure, you can abandon said business entity with less damage to your personal name and reputation. You can't skip out on the taint completely, but it minimizes the damages and makes it easier to start over. An example bad case scenario would be someone hacks your popular product and exploits it to push malware all over the place. People will remember that product as the one that got hacked, and the associated business name might be irrevocably tarnished.
You don't have to incorporate right now to gain the benefits of a business name. "Doing Business As" or "Assumed Business Name" is a time-honored construct for your situation. You could very easily switch over to being the business "A Blue Scarab Production" by changing your website and the splash screens of your apps. You can then hire a lawyer later on for incorporation considerations once you start growing in sales.
