Performance enhancement for list of talks

[patrickmineault]

I notice that the homepage freezes for a bit while talks are rendered to the DOM. This could be fixed with a virtualized list component that only renders list elements when they're on the screen, for example https://tangbc.github.io/vue-virtual-scroll-list/#/dynamic-size.

How open are you to refactor some javascript to use a lightweight component library like vue.js so we could easily integrate a virtualized list? For reference, with the linked component, solving the performance issue would be as easy as integrating this snippet:

<virtual-list class="list"
  :data-key="'id'"
  :data-sources="items"
  :data-component="itemComponent"
  :estimate-size="80"
/>
