The last few tech conferences I've attended tried to use txt voting from mobile devices. They forgot to include the destination number on the instruction slide and just listed the voting codes. Everyone just shrugged and started scanning twitter. Voting was light and it was frustrating to wait.
We are looking forward to testing it out on other events, with higher voting rates. We tested monitoring mentions of popular twitter accounts and results were absolutely impressive. So if you have any good examples feel free to drop us an email andthewinneris@beyounic.com
This looks much better. And great design.
