If a question on an English-language Stack Exchange site does not contain at least one uppercase and one lowercase letter, our quality filter should reject it.
(We can make exceptions for sites which don't use a mixed-case alphabet, such as Japanese Language and Usage.)
The quality filter currently rejects neither all-uppercase nor all-lowercase posts. I've checked.
The best Stack Exchange users use mixed case. If an asker is too lazy to use their Shift key, their question tends not to be of very good quality.
Don't take my word for it. You can see proof. Sam Saffron helped me write a Stack Exchange Data Explorer query which lets you see with your very own eyes that what I am saying is true.
Single-case askers tend to ask poor-quality questions such as:
- "gem 'websocket-rails' and its scalability
- how to set particular value as dropdown default value in edit button click event in php
- Changing copied arabic text font in document richtexteditor
In addition, posts which use only uppercase or only lowercase — even if they aren't riddled with typos or grammatical errors — tend to be hard to read. Capitalization aids readability.
Why is this proposal not a duplicate?
This proposal is not a duplicate of the older proposal "BLOCK QUESTIONS IN ALL CAPS". This is because it also deals with all-lowercase questions.
All-lowercase questions are 50 times more common than all-caps questions. Stack Overflow gets only about 100 all-uppercase questions per year; see here. Yet it gets about 5,000 all-lowercase questions per year; see here. (These statistics are for Stack Overflow only; the rest of our network wasn't considered.)
I suspect that the older proposal was declined for two reasons:
All-uppercase questions are rare.
Therefore, the effort required to block all-uppercase questions is too much.
This proposal is better. For just a bit more effort, the Stack Exchange developers can get a much richer reward.
What do you think of my proposal?
Agree? Disagree? Thoughts?
PS: This idea is modified and adapted from an older idea by Stack Exchange user Gilles. My dear sir Gilles, I thank you.
There's even a chat bot which automatically detects questions with all-caps titles and alerts interested users and moderators.
