Can anybody suggest how to make this less "opinion based"?

https://superuser.com/questions/895454/what-features-are-important-in-a-scanner-sheet-feeder-for-old-personal-documen

In particular, I'd like to keep the question useful to other people doing scanning at home.  I do think there's a useful / stable question here, which is the one that emphasizes aspects that are common to users who scan rather miscellaneous document collections for disaster recovery and space saving.  So I don't want to end up with it being too specific to me by responding to every comment (it already headed a bit that way perhaps).  I think user291737's answer demonstrates there are useful answers to that question.

It would be great if people who think it is can say why, and how to remedy that.  I'm unable as the questioner to see the "primarily opinion-based" nature of it -- I'm guessing that, rather than being a problem with the question as I intended it, this is because of some tacit assumptions I have that other people don't share, but I don't really know.

I've already edited the question to clarify in response to comments, but the question hasn't yet received enough votes to re-open.

I can see that the title sounds a little "opinion based", but I had hoped the actual question content made up for that.  I find it tricky to always make the title say *exactly* what the question is asking for, while still providing a quick summary that allows people to see if they might be interested in the question.
