Question: I was recently speaking with my manager, who stated that while my work is satisfactory, they've been noticing I'm spending a lot of time of Stack Exchange. I find Stack Exchange to be very informative and helpful in my work.

Particularly considering this Stack Exchange site has many users who spend a large portion of their time on here, how can I explain to my manager how useful Stack Exchange is for me?

Answer: 
You start using this gem:

```
try
{
     //Do Something
}
catch (Exception ex)
{
     if (DesignMode)
     {
           Process.Start("http://www.stackoverflow.com/search/q=" +
                         System.Web.HttpUtility.UrlEncode(ex.Message));
     }
}

```

Seriously, though, if your manager can't see the value of StackOverflow, you need a new manager. There's no good answer other than that.
Depending on your situation and the relationship you have with your boss, you might be able to document specific instances where you asked a question, got an answer, and therefor saved valuable company time. 

Couple that with specific instances of you answering a question that required you to become better at your job. This shows the long-term value of allowing you to spend a measured amount of time on SO/SE. 

The second paragraph is probably the more tricky one to convince the [PHB](https://en.wikipedia.org/wiki/Pointy-haired_Boss) of. They may or may not care / believe that the site helps your continuing education.
