I see nothing wrong with that.
As luck would have it, today some random stranger recognized me from my Stackoverflow profile at a Panera and asked me to help him debug his Django app. It was straightforward to fix because the error message described the problem exactly, but, for whatever reason, it wasn't apparent to him. I pointed this out, explained the problem, and showed him how to look for additional information based on the error message. Maybe this sounds softer in person, but there is nothing wrong with reminding people to pay attention to error messages, and the importance of giving people adequate amounts of information when you ask for their help.
Now, as a person who's answered many a question on Stackoverflow, I've had people threatening physical harm to me and my loved ones, as well as setting up Twitter accounts to harass me. To their credit, Stackoverflow admins always take swift action when actual harassment occurs. However, Twitter and Facebook seemed rather uninterested.
