Conference WIP pt.2

Working on some conference branding for my church.. wondering if this icon makes sense outside of my head.
A + Conversation Bubble = Icon.

The conference will be based around how we do church, based around personal conversations with the people who come. We want to cap the event at like 150 people so that we have about 1:1 or 1:2 (staff:attendees).

Thoughts?
