Sorry I’m a little late to the party, but if you’re looking to keep up-to-date with alternative views and sources on issues surrounding our nation, a good aggregation site would be Singapore Daily.
The posts from the various sources are neatly categorized each day into broad topics like anti-foreigner sentiments, housing etc. and more specific trends like commotion over the recent panda imports, controversy over Diner en Blanc, National Day Rally etc.
Read them with a critical eye – not all thoughts and arguments are credible or well-supported, and certainly the voices online aren’t representative of Singapore either. But it is a good exposure nonetheless and the site helpfully aggregates these for you. I’d seriously recommend you use this rather than depend solely on socio-political sites like The Online Citizen or Temasek Times.
