You have to read a lot if you want to know or learn something from the forum. There are many types of posts in the forum. Every post is very helpful. There are replays from legendary to newbies through writing. So if you want to learn something new every day then you have to practice a lot of reading, which can make you legendary in future.
Is like you're saying members should start reading to become legendary member, that's not how is suppose to be. You know some people can read because they have to not because they love to and some can read for the love of it and they do pick out informative things in what they're reading, and it gets more interesting.
I even think some people just explore the Forum to read post and threads to kill depression or to forget something that's bothering them (I know we have people like that on the Forum), this Forum has changed the mindset of many in different ways, I mean positively. So for you to say someone has to read and learn to become a legendary member in the future then the aim of reading and learning doesn't march at all.
