1./ Advice is useful when it originates from an experienced source (aka: "wisdom"). This is separate from what is known as "common sense"...the sort of notions that everyone inherently knows to be truths or conventional wisdom. In my experience, exceptionally few 14 year olds possess this.
2./ The statement you made exposes this rather handily:
In this context, "threads" = "discussions". Take your statement, substitute the word "Threads" with "Discussions" and then tell me if you feel it's still valid.
Huh? How did you arrive there?
