Frankly speaking, most guides are regurgitated. For instance, how to post properly, how to trade Bitcoin, how to spot fake giveaways, how to rank up, how to impress Satoshi, how to report scammers, how to flatter theymos.
We need some innovative ones, but then the forum stats have also been overused

It does not matter if you can make a better thread and OP of the best thread (on same problem) is inactively on the forum for too long and is not able to update that thread. Fundamentally, the content you write is a matter.
As you can see in other sections, people are just dumping many non-sense posts on many threads. They still don't know what's the feeling of having a thread and it's very satisfying to discuss something that you knew very well. There's no restriction on good discussions, It just shows that having threads have more benefits than the typical reply posts.
Replies in Mega spam threads are useless because no one read such replies no matter how you those posts are. For Mega spam threads, simply ignore and don't reply. For the others, I feel well to reply to help OP in a very few pages of each thread.
Threads composed by good OPs are much more contentful and helpful, I agree but don't self-restrict how we contribute to the community like that.

Please don't quote the whole OP like that. Instead, please use @OP or simply reply if your target reader is OP.
