I don't think any forums period are beneficial to one's aspirations (mines included). In fact forums are the WORST places to be at if you ever want to achieve something lol.
They drown you of your time, you may sometimes become addicted to it, too many opinions from people with different perceptions and agendas and if you start to engage in conversation it can only get worst. Same goes with facebook or any form of social media... reading email also falls in that category.
I enjoy coming here to read some posts, engage in conversation every now and then or just lurk but truth is forums are like that group of friends that always likes to party... you are going to have fun when ya go out but deep down you know if you go down that route you will NEVER get shit done.
