In multiparty systems, it is possible to have a single-issue party which is actually electable (see the Pirate Party in Sweden and Germany). But in the US, any party must have a completely defined platform which is acceptable to a majority - or at least a plurality - of voters.

That is why the Libertarian and Green parties, both of which receive quite a few votes, are never elected. And that is why the proposed new party has very little chance. If its platform is defined by San Francisco hackers, there's a good chance that I will agree with half of the platform and strongly disagree with the other half, and most of the country will have the same reaction.
