             EventBE.displayCount())">
            <li >

   <span data-bind="if:EventBE.WhoElseAttends.length <0">No Attendees</span>

Here's the working HTML:

<div class="slide">
    <button type="button" data-bind="click: readMore, visible: displayCount() < WhoElseAttends().length">Read More</button>
    <ul data-bind="foreach: WhoElseAttends.slice(0, displayCount())">
        <li>
            <span data-bind="text:FirstName"></span>
            <span data-bind="text:LastName"></span>,
            <span data-bind="text:Company"></span>
        </li>
    </ul>                  
    <span data-bind="if: WhoElseAttends.length <0">No Attendees</span>                    
</div>

And the accompanying Knockout view model:

function viewModel() {
    this.displayCount = ko.observable(2);

    this.readMore = function() {
        this.displayCount(this.displayCount() + 2);
    };

    this.WhoElseAttends = ko.observableArray([]);

    for (var i = 0; i < 10; i++) {
        this.WhoElseAttends.push({FirstName : "John", LastName : "Smith", Company : "None"});
    }
}

ko.applyBindings(new viewModel());

I've also rendered this code in the following jfiddle: http://jsfiddle.net/Bg5CF/17/
