I guess following the principal that the sun rises in the east, it would appear that Yahoo! has chosen to fire its opening salvo in Singapore, though I can't get the beta site URL to open (I would be interested to hear from any Singapore-based readers who can view it). The East is red with telco blood, and I guess it's flowing this way, though I don't see any signs of PSTN breakout in the European sites I've checked so far. (Uber-thanks, Hermano Nordico!)
UPDATE: A very helpful mega-uber value reader points me to the right URLs. Thanks!
