I had asked this one the Meta SE before, however due to many titles involving code from SO, it was not taken too lightly. I am going to reform this question and ask it here as it is really mostly relevant here.
When a user is submitting a question, just as the 'bad title' pop up comes up, another pop up, which tells the user that their first letter in the sentence is not capital (upper case).
There is literally no reason why a title should not start with a capital letter. The only reasons I can think of are:
- If the title starts with math. In which case is bad practice anyway however this is a separate issue.
The benefits of this is that many questions are in need of edits however only have the first letter of the title to be capitalised. This will save editing time for users and keep the site cleaner in a non-harmful way.
