He didn't ask for the best advice. He asked for opinions, and I think he got a bunch of reasonably good opinions.
I have a problem right now, and I am going to ask on a forum. I am likely to get some really good advice, and then, after being educated, I will no doubt be better armed when I start in with screwdrivers and wrenches. I will know better what to look for, before I spend hours looking. If somebody says "well, dummy, what you need is a more experienced mechanic" I might secretly agree with him, but I shall ignore the dig. (It's a fuel leak).
