For those who ask "Should I get an LLC?", the answer is....LLC stands for Limited Liability Company. It is a legal entity that limits your legal liability against accidents, creditors, etc. So...are are your liabilities (both present and yet to come) and why might you want to limit them?
If the answer is "I don't have any liabilities, now nor ever.", then why would you want to go through the legal hassle of creating and maintaining an LLC?

FYI - I'm "technically" a CPA, but less "accountant" and more "financial planner who also has a tax practice". I have never worked in industry or audit. Moreover, IANAL. (I Am Not A Lawyer)
