I think its just part of the cycle. Like Patrick said, there are a lot of different social media platforms now. Plus You have to look at other things also. We always had a few guys that would give great detailed reports with a lot of pics that aren't really active anymore. Some have moved on, some have moved, and some have sadly passed away. Just take a look at the all time report leaders and you will see what I mean. I think the Hall of Fame definitely helped get posts up too back in the day as people posted all kinds of pictures of different species and not just bass. With the lake getting crowded it tends to keep people more hush about their fish too. I still love the forum and have met some great guys throughout the years on the CFF. Here is a chart of the guys who have surpassed 100 fishing reports all time....
