Why shouldn't I care what model/make/year my bicycle is? We often get questions on bicycles.stackexchange about identifying a bicycles manufacturer, model, make, and year.  Often these questions are downvoted or closed -- usually with a comment attached to them that it's not necessary to know the exact model/make/year of a bicycle if you want to fix, repair, or ride your bike.
Why should owners not care about the model/make/year of their bicycle?
Especially when it comes to less expensive bikes (aka BSOs) and BMX bicycles?
This is intended as a canonical question that we can point closed questions to.

What is the purpose of a serial number?   (generally not helpful for identifying a brand/model)
The problem with the question is not the owner's interest in the answer - it is clearly there. The problem is that the answer has almost no value for the community of this site: 


most generic bikes are hard to identify to begin with
most successful identification will be based on a photo which cannot be used to answer the same question again because questions and answers are centred around searchable text and tags.


In total, there is too little to gain from answers for the community in the short and in the long run to make them worthwhile. Hence, they should be banned in my opinion.
