Answering for myself, I didn't have anything to say when I was a noob. It's that easy for people like me.
Of course, we see a lot of pointless topics made by newbs who haven't perused the forums out of laziness to see decks and topics like the one they were thinking of making. When I got here, the forum layout was more than daunting. I had no idea what boards were for what, and it took quite a while to figure out how things worked. It's pretty convoluted, and that's enough to put off a high percentage of internet-goers.
It's also very hard to get involved in the community and get feedback on your work. Unless you have a title, it'll take months to get people to listen and acknowledge you. -That- may need changing, but I doubt we could do anything about it outside of toning down on the number of titles.
To say vets need to post in newb topics more isn't really realistic. We've posted in a hundred of the same nature in the past, and it rarely has any impact. You just get tired of repeating yourself.
