Hopefully not. While I'm disappointed that Twitter is supporting xAuth, the move to OAuth should bring well needed security enhancements. Twitter has had the previous date set for at least six months now I think, and now they're even extending it.

Are there any stats around how many applications have already upgraded? I can only assume that a low uptake is responsible for the delay. That low uptake could be explained by the large jump in programming skill required.

There are OAuth implementations available in just about every language.

I think the challenge isn't programming skills, but understanding something inherently complex: how do you safely give third parties privileges to act on your behalf?
