Buy Local: Make Mailing Lists Dead Simple with Fiesta.cc

10gen veteran Mike Dirolf has been working out of Dogpatch Labs on an app that makes creating mailing lists as effortless as humanly possible. Just compose an email, add the recipients, pick a name for the list, and copy that name @fiesta.cc on the email–thailand@fiesta.cc for people you want to make jealous with updates on your backpacking trip, for example, or mememakers@fiesta.cc for the best 3.0 people to spread the word about your pet start-up/project/video of the moment. “Seems like group texting services are all the rage right now, and I thought there was some room to do something similar for email,” Mr. Dirolf said. Check it out at fiesta.cc. —Bb.
