I am having a little trouble with "go for".
Here's a short explanation: My understanding is that if an user is not posting a log or command output with detailed information, then the threads won't get anywhere because even advanced users either gave no reply at all, or else offered some vague explanations. In other words, ambiguity in replies can extend to several tens of posts in a thread eventually ending when an advanced user may ask relevant specifications and at least give you a hint of what an user is looking for. Or to put it another way, that means when someone is asking these questions, they should post an exact error message and not an interpretation of that message. Doing it this way is necessary for the community to understand the problems that they are dealing with.
Here's the excerpt: I've seen threads go for pages and all someone needed to do was ask for simple command output.
My attempt: Forum threads that span hundreds of pages/That type of thread frequently extends across multiple pages...?
Grammatically speaking, does it have something to do with go long? Is this sentence grammatically correct, and does it also make sense? I'd like to get the English explanation for that expression in this context. I'm not really sure about that. I'll appreciate any help.
