Why do yahoo put your question in random place the not related to your question ?

There is an algorithm the site uses to place questions and sometimes it places them in the wrong category, because it could not locate enough keywords to make a better selection. All users may relocate their question after it is placed on the site by the system. As to why any user intentionally relocates their question to an inapplicable subcategory, only they know (and is an inappropriate question to post here, as are all questions about the users themselves). 

It is related as best as the system can figure out. Not even the CIA could place some of these questions correctly with all their spy software. The system can not read your mind, so make sure there are enough keywords in the question to help the system.

YOU have the power to put it anywhere you want. 

what's the point of complaining, when YOU have the power to fix it? 

*Your question ends up in the wrong category*

Step 1: Press "edit category"
Step 2: Click on the sub category and main category in which you want your question
Step 3: Press submit

What exactly is so hard about that?

Its Based on Key Words so when you post your Question Yahoo takes a Guess on where it thinks it should go 

Its Not Perfect so if it does not get it Right you can Fix It 

After the Question is Posted to Correct it click Edit then Click Edit Category from there Select the Right Category for it and click Submit and it will go to the Right one
