Yahoo Mail has been screwed up or down altogether since this weekend, causing "anguished cries" from the Bay Area according to one tipster. Apparently local nerds are being unfairly denied their Craigslist responses. Widepsread and ongoing problems — dating back weeks or months, as noted in some reports — are blamed on Java conflicts, the buggy beta version of Yahoo Mail, and rotten server farms. Also solar flares and malicious pixies.
