If he wants to learn by doing, don't ask, do. If he wants to take the shortcut and get the "right" answer right away, it's "get an interface". Going online for advice on how to do it wrong makes no sense. Strike that. Advising how to use that hardware for that application doesn't necessarily help the OP.
Question: I've got two old bicycles and a lawnmower. How do I build a decent car out of these parts?
Answer: Buy a car.
It's not the advice provided, it's the snark in the responses I find troubling. He needed a mic preamp, he found something that is effectively a (poor) mic preamp and asked how to get it to work with his computer setup. Your response, for example, was not helpful at all aside from perhaps trying to make the OP feel foolish for asking(?).
In the same way you perhaps don't like me calling you on it they would likely not take kindly to your veiled insult(s).
