WOTC - Quarterly referendum

I asked this question in the Wisdom of the Crowd:

Should Singapore introduce quarterly referendums like in Switzerland?

Here are the responses: (39 Votes)

64 % - It will give the people a chance to express their views on important matters.
28 % - The results of the referendum should guide Parliament in its final decision matter, but should not be mandatory.
5 % - It will be too costly to organize the referendums.
3 % - The referendums will be poorly participated.
