Bad swag list: - Bottles - T-shirts - Chargers - USB sticks - Mugs - Socks - Notebooks - Tote bags - Keychains - Coasters - Pins (I have infinite amounts of each of these, collected at conferences)

I once got a branded wooden cutting board as a holiday gift from a vendor. It might sound odd but it is hands down the longest kept and most used bit of swag I have ever received.

The @digitalocean beach towels for Rubyconf Miami were peak swag. Everything is downhill from there.
