Summary extension for rich text fields

Here is an extension that allows you to take a subsection of a rich text field and display it as a string.

public static string GetSummary(this XhtmlString input, int? summaryLength = null)
    if (input != null)
        var summary = TextIndexer.StripHtml(input.ToString(), summaryLength ?? 0);

        summary = HttpUtility.HtmlDecode(summary);

        return summary + "...";

    return null;

I've found this extension useful, especially for displaying search results.

Just a quick example so folks don't have to keep reinventing the wheel.

Seems like a very flaky way of getting a summary. You don't know where the rich text is going to cut off. You'd be better having a specific field for summaries displayed across a site that you use and is limited to a specific length so that it can match designs and doesn't break with responsive grid sturctures.
