Yes I think we're talking at cross-purposes here. Perhaps App.net really was better, that's great - it means we know how to solve the problems of twitter (given I haven't heard exactly how it was better, that makes me sceptical).

But I think what you mean is _replace_ twitter, which is not what I was getting at. That is not just a tech or marketing problem but a business problem. I believe that's possible too. But the skillset required is probably outside of the average HN member, so I was tailoring my comment for a tech person.

Another way tech people can contribute is making chrome add-ons that improve twitter, demonstrating how it can be better.

Again, that's separate from launching a company.
