I had my doubts about Diaspora, but now I know for sure: it will be a complete fiasco. Those are horrendous errors that show that those guys have completely no idea about web programming - and I can't see them learning it quickly (certainly not before planned release date of the final version).
Sad thing.
Indeed, the level of errors shown in this demonstrates that they would probably need about 2-3 years of experience to be decent at doing work like this. I think the best thing they could have done is hired 3 skilled developers to work for 6 months at $5k a month.
Which begs the question - where did the money go ?
What they've released looks like your average weekend github side-project. I suspect a large % of Hacker News members have projects like this (though hopefully with better security ;-)). So what did they spend the money on ?
