I feel mostly useful on this forum on technical boards where people ask questions about bitcoin wallets, but there are other boards that are also useful. If you go to altcoin board for example, ask questions and see some quality replies/answers from people. There was a friend I told to ask a question about an altcoin wallet when he was unable to see his altcoin reflecting on his wallet while showing confirmation on the altcoin blockchain, he got answer to his question on this forum as they told him what to do. That was on altcoins discussion. There are some useful topics on the altcoin boards also.

On trading discussion, you can see good discussion there. People often come with questions that were answered on trading discussion. But most merit sources are not present on that board because they are mostly technically inclined.

How about gambling boards, scam accusation and reputation. If someone using a gambling site that has announcement thread on this forum felt cheated by any of the casinos or gambling sites, you will see the person create a scam acquisition against the gambling site. If provided with proves, there are many cases like this that were resolved. Although the scam accusation board is not only about gambling sites but all other sites that people on this forum know very well and others beyond this forum. You can also see people discussing about gambling addiction, recommended gambling sites and offers on games and rounds. You may see it not useful but if you think about it deep downs, they are useless boards as well. The presence of some gambling sites on this forum help some people to avoid fake and scam gambling sites just as we recommend good bitcoin wallets on the technical boards.

But what you can say is that the spam on the bitcoin technical boards are significantly reduced like to almost zero if compared to other boards that spammimg and low quality posts are frequent.
