SXSW Interactive saw a lot of new applications getting their first walk through the crowd. Success depends on use, and lots of it. Here are some of the more interesting flavors of network.
Called a kind of "sixth sense" by company CEO Paul Davison, this app merges social and location and runs constantly in your phone, pulling up information about people around you through Facebook and engaging in nonstop information sharing.
Aggregating information from Facebook, Twitter, Foursquare, LinkedIn, and others, it's constantly searching for relevant connections between you and people around you — even friends of friends.
Defying the now-now-now bias of social media, this app allows you to share your intended future location with friends. Taken to its absurd extreme, it'll allow friends to carpool to your funeral.
Dating as game, assembling a profile of your interests based on where you actually go and what you actually do, and sharing it with others who might be interested in hitting that — while keeping personal information private.
An entry for those interested in the "quantified self" — people who want to monitor, record, and share their wellness information, from steps taken to calories burned — Jiff bills itself as "the Facebook of Health," connecting users to friends as well as medical pros.
Part of the family of apps turning life into a game, GooseChase lets users join worldwide scavenger hunts or construct small ones for friends, with leader boards and everything. The barely legal bachelor party implications alone boggle the mind.
A nonpartisan, web-based platform allowing users to nominate presidential candidates and build a database of qualities that will be used (along with a lot of real-live name-collecting petitions) to find the candidates who best represent real America — and then get those names on the November ballot.
