This may come off as a rant - and I guess maybe it is one (at least a little bit), but here goes...
Why do users re-answer questions which are clearly and obviously duplicates instead of flagging them as duplicates?
I can easily understand a new user not knowing that minor variations on what boils down to the same question get asked repeatedly, but we quite often have long-standing experienced users churning out the same answers to the same questions over and over.
For example, a recent question: How to revitalize wood screw hole where screw won't stay tight?
with a selection of duplicates:
- How do I rehang a wooden door with worn screw holes?
- What are some effective methods to fix a worn out screw holes of a door hinge?
- What do I need to do to fix stripped door hinge screw holes?
- Do I need a wood hardener for worn door hinge screw holes?
- fixing stripped screw in soft-wood door frame?
- How to mount screw in a worn out hole
- How can I repair screws in furniture with stripped holes?
- and more of the same ....
How do we encourage those among us who really should know and recognize a duplicate question when they see it so use the duplicate system which is in place?
Is it too difficult to find the duplicate(s)?
What else hinders us from using the duplicate system?
This behavior is certainly not unique to DIY - I often see it on Electronics too.
