Author here—this is the best part of HN. I perhaps took the idea too far. Any iOS push notification can be up to 4kb, and Yo’s API shows that each Yo includes a created time, sender name, avatar, User ID, message status, and more. That’s for traditional Yo’s; newer ones can include a location or link or RSS feed item for a news update, which goes far beyond the core concept. So on a technical level absolutely, a Yo is far more than bit. Conceptually though a single ping—a single bit—could contain the same information, like a single dot telegram, with you or your local device recording the time received. If you only Yo’d with one other person, the time and the sender and the message they intended to convey would all be data points you would assemble in your head with the ping to get the full information. Anyhow. That’s perhaps taking the idea too far :)
