I've just recently gotten into development with the Live Search web service. I've already encountered a problem. The Result.SearchTags property is documented as having individual tags delimited by a comma. But, if a search tag contains a comma, it's not escaped in any way; which blows parsing SearchTags right out of the the water.

For example, there's a meta tag at http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=542568&SiteID=1 in the form: <meta name="Search.MSForums.ThreadName" content="Process.BeginOutputReadLine() just fires events all at once, not in real-time! ">

The comma causes anything parsing the tags to think "not in real-time! " is a tag all its own.
