Couple things I've noticed during the last few months that are present in every country and city I visit.
Hammering - yes that's right, everywhere I've stayed there is some sort of hammering going on throughout the day/night. It's like the this entire part of the world just discovered their dad's tool box and are convinced that everything can be built/fixed with a hammer
711 - omnipresent, these green bastions of familiarity & comfort are even more prevelant than in LA.
Soccer - at least 2-3 channels in every place that we've stayed (that had a tv) are devoted to soccer 24 hours/day. I'm definitely a fan of the "beautiful game" and being able to watch Premier league at all times is most entertaining, but local Filipino teams floundering around on a brown field might not need to be televised.
Akon - yep, he's worldwide
Where have all the trash cans gone? - I really don't know but they've hidden them somewhere. With trash strewn about in many countries in SE Asia, you'd think a simple answer would be get some trash cans, but then I guess you'd have to figure out how to collect the trash, etc and municipal services are not this part of the world's strongest attribute.
Some random observations....
