I agree that such titles need improvement. But looking at the data, I do not find much indication that the OP wants to participate in a broad discussion. Most often, it's just poor writing form: writing "Has anyone successfully installed (this) on (that)" when the actual question is how to install that thing. 

Another, strongly related, mistake is writing something like "Can anyone help me with this wireless driver problem" instead of actually describing the problem. It's not conversational style that's the main issue, but lack of specifics.  

I dug up some stats: 

- [Can someone](http://askubuntu.com/search?q=title%3A%22can+someone%22): 70 questions 
- [Can anyone](http://askubuntu.com/search?q=title%3A%22can+anyone%22): 57
- [Does anyone](http://askubuntu.com/search?q=title%3A%22does+anyone%22): 44
- [Has anyone](http://askubuntu.com/search?q=title%3A%22has+anyone%22): 36
- [Can anybody](http://askubuntu.com/search?q=title%3A%22can+anybody%22): 16
- [Does anybody](http://askubuntu.com/search?q=title%3A%22does+anybody%22): 14
- [Does someone](http://askubuntu.com/search?q=title%3A%22does+someone%22): 5
- [Has anybody](http://askubuntu.com/search?q=title%3A%22has+anybody%22): 5

All of these are dwarfed by 

- [please help](http://askubuntu.com/search?q=title%3A%22please+help%22): 271 questions. As in "update problem, please help"... 

So, I suggest addressing this wider problem of insufficiently specific titles. A title matching 

    ^.{0,30}(^|\W)(anybody|anyone|doubt|help|please|problem|question|somebody|someone)(\W|$).{0,30}$

<sup>case insensitive, in whichever flavour</sup>

probably needs work and should generate a warning message, like the one on [Math.SE](http://meta.math.stackexchange.com/a/17012).
