Don't judge someone's knowledge of bitcoin and bitcointalk from their ranks because there are lot of exceptions to explain the ranks is not actually determine everything, just go to the technical board where you see low ranked members who have more knowledge about how bitcoin things works than some random legendary posting in bounties or altcoin board.
lol... but that's the salient truth, the technical aspects is not what one can dabble into anyhow without having the knowledge or experience, that's why some will maintain their coast, but that doesn't mean at all, take for instance, we have it that some students may be good in English than in mathematics while others in exchange of the two, but few ones were actually good at them both, same is also what we can see happening here, but the merit system is so perfect enough that if you gat nothing to offer, then that limit your growth as well on the forum.
And there is something you should know that not all skilled individuals where skillful through University and sometimes the ability to know is within you.
education is not the measure of soundness, hardworks, deligency and knowledge, to me it only gives additional beauty to talent and acquired skills, though we learn from school but I've seen some students who have nothing to show off despite their level if been taught in school, they can't just assimilate through education except by other means, the richest people were not learnards but just few are.
