Hi Robert, how have you been? 
After reading your article, I came to a rather different conclusion
- that there has to be serious problems to warrant a concrete
uprising. Naturally, what constitutes "serious" and "concrete" is
subjective and debatable.
You mentioned "Water Margin". Like the present Myanmar case, this
came about through rampant misrule. Is Singapore in the league? The
opinions contrast between some blogs and forums, and the people I
know outside the political internet circles.
As for "common modus operandi", there is - pockets of them, that
is, rather than one concerted effort. Forums, after all, are
diverse. There are people supportive of PAP, people supportive of
other parties with some supporting only some of them. Some take
forums for fun, some take it as a breeding ground for mobilisation,
recruitment or build nucleus for a new party.
"Reverse psychology" games, malicious or otherwise, are also
becoming popular (opposition supporters pretending to be the
opposite and vice versa), something not seen before. When the
agenda is common, some unite.
Regards
