When I found Flyertalk, I was amazed at what I found and what I was learning about something that was quickly peaking my interest, frequent flying. At first it was for pleasure and then I got the chance at business flying and was hooked.
I read posts everyday from Rudi, PremEx, Baobab, and Merry. I didn't know who these people were but I did enjoy reading their messages and usually found a tip in every post. Now most of the postings are about mypoints, or how many United FA's sit in FC, or how quanity of posts is better than the quality of the posts. And as Merry has pointed out, a lot of the "old timers" have stopped posting.
I am in the same boat as QuietLion and Geo1004 above me, I am getting to read the Continental and Marriott forums and starting to skip the rest as it is not giving me the information that used to be here.
