- `{}` is not falsey so Handlebars would try to render the block (see http://handlebarsjs.com/builtin_helpers.html#conditionals), therefore with a `nick` of `undefined`, which breaks `colorClass` (doing `undefined.length)
- There does not seem to be a way to check for empty objects in Handlebars (sigh) so checking `from.nick` seems like the most reliable way to check for a non-empty value. Alternatively, we could use a helper to check `{}` but meh.
