Yeah, the problem with threads on Bitcoin Discussion, Altcoin Discussion, and similar, is that there is rarely anything that could be considered a defined "end-point". Look at some examples from the first page of Bitcoin Discussion, threads such as "Do you think cryptocurrencies will be gone anytime soon?" or "Can bitcoin help countries in economic crisis?". You could go back and forth on these topics forever; everyone could have an opinion, even if it's been said before, and there is no 100% right answer. Even if this thread is dead for months, someone can come along a bump it with their opinion and not be off-topic. Furthermore, the OP very rarely sticks around to read what is being said or discuss it, and therefore very rarely locks the topic once they feel the thread has run its course. Once a thread in these boards hits 5+ pages, you are very unlikely to read anything worthwhile.
