> This is a little off topic but these comments make me wonder: why are lawyers so reluctant to give informal advice?
Because an attorney-client relationship is created when the client reasonably believes it to have been created. As a result, you have to be really fucking clear that people are not your clients because, when making the determination of whether someone has reasonably determined that someone is their lawyer, courts look to what the average bloke would think - i.e., a total dumdum. So you really have to hit people over the head with the fact that no, you are not their lawyer.
So, the second part of this is that when an attorney-client relationship is created, the attorney has a tremendous amount of duty to the client, and, if the client acts on the advice of the attorney and gets results they do not like, they can sue the attorney for malpractice.

Are you a licensed Professional Engineer? If so, for the love of Odin's beard, stop giving informal advice, as you are exposing yourself to professional liability.
Licensed professions - accounting, medicine, law, professional engineering - have extremely high duties of care to their clients. They are exposed to malpractice liability when things go wrong. They have ethical obligations. It can be extremely hard to fire delinquent or terrible clients.
To put it a completely different way: lawyers give advice as their job. There is no such thing as "informal advice" from a lawyer, the same where there is no such thing as a "pick up game" with an NBA player. It is their primary occupation. I don't do it for free - I charge a pretty stiff hourly rate. And every time I take on a client, it has impacts on my firm's malpractice insurance. In fact, I cannot take on clients without the explicit approval of the managing partner at my law firm - I get his written approval for every single one. To make it clear, the managing partner is the guy who, if there was a war between all the lawyers, gets to wear the biggest, fanciest hat. So, no, I am not just going to do the thing I do for my day job as a favor to someone else, any more than your computer programmer friend wants to fix your iphone.
Does that go some distance to answering your question?
