It definitely discourages effort-posting in GBS, but the mods are too busy policing words to do anything about it.
This was my biggest turn off when I checked back into SA/GBS after years of being away. (I admit I returned for the Everest season because I like the thread tracking rich morons paying $50,000 to pointlessly freeze to death on a mountain and I have bets laid.) It seemed like mocking "effort posts" whether good or bad was all most posters did anymore. This obviously led to very few threads with worthwhile content from even being posted, because why fucking bother.
In 2004 GBS was overloaded with interesting threads to read, you were spoiled for choices and there wasn't enough time to read them all. Now, bupkis and it's why I eventually found this forum.
