Please read this [post on meta-stackoverflow.com][1].

The key message is: You have only 16 characters in your title, so don't waste them.  
Read the [good/bad examples][2] and look if you agree with them.

>**2. Keep it short.**

>You don't have to put all the details in the title. There's plenty of space to expand your question in the body of the text.

>Likewise, don't insist that your title be expressed as a perfectly
formed English sentence.

>**3. Lead with the most important words.**

>[These][3] [articles][4] discuss how people read web pages, based on using
an eye tracking system to monitor users.
For Stack Overflow-like pages people read most of the first
and second entries (the bars of the "F"), and then scan down the
rest of the list, reading on average the **first 16 characters of each line.**

>**4. Don't start with "How do I..."**

>Writing in that style ensures that you title will fail
criteria 1-3, and get less attention than it deserves.

>This is a question site, and people will understand your titles are questions.

To be fair: There is a certain amount of [people who disagree][5] with this.
