Too professional? No - it is populated by amateurs who delight in designing with and writing code for the 6502 and its relatives. Some of us either have or have had careers in the industry and that will show - there are always in-company rules about how drawings should be drawn and how code should be written, indented, and commented, and in general we will tend to follow those standards.
So if someone suggests that, for example, your drawing might be improved, it's just that: a suggestion that makes it easier for them to help you, by reducing the amount of work they have to do to do it.
It can sound kind of bossy: you WILL draw your drawings THIS way! but it's not; it's providing you with another tool. You don't need to do it, but if you do, you're more likely to get help. 'Netlist' drawings are almost universally disliked: they contain all the information you need to make a circuit board, but generally they tell you nothing about the circuit topology until all the networks are joined up. It's one of those things where _you_ know how everything fits together, but nobody else does
So hang around a while...
