This is all true, but one needs to be aware that these forums are also chock full of "forum folklore". You'll get all kinds of advice and lecturing which is driven by what has been posted before rather than what matches reality.
Mixing DOT-5 brake fluid with DOT-3/4 is always a fun one. Folklore is that it will poison children and kill puppies. Reality is that they are, by law, compatible and mixing won't do anything more than create a fluid with unknown boiling points, but this is true of mixing any two brake fluids (and it is true DOT-5 is not compatible with ABS brake systems, but that's a separate point).
Pretty much anything to do with turbos is another fun one, as many folks have no idea how turbos work but have lots of opinions on tuning them.
Anyway, the point is that the comradery is great on these forums, they're a lot of fun, and you can find good info, but don't take any info on them as gospel.
