Just wondering if there are any Valve employees who are users on this site who answer technical support questions. I have what seems to be a fairly localized problem with steam and I'm wondering if I can expect to hear a solution from someone with some white-box understanding of the issue.
No, and even if there were Valve employees here, you would be better off asking your question on the official Steam forums or filing a support ticket directly with Valve.
We are experts in gaming and things related to gaming. We are not expected to be experts on the behind-the-scenes understanding of products as you are requesting. As such, questions that require that kind of knowledge are off topic.
