The Lib Dems have a reputation for saying whatever people want to hear, and it was suggested before the election that they would turn around when they were in power. I didn't think so so I voted for them, but I've now learned the error of my ways. Clegg's lies about the tuition fees policy is but one example. I doubt the public will be fooled a second time.
I'm sad you think so. So what we say/said on Europe, on Immigration, and on the Deficit even before the election, that was all "what people wanted to hear" was it?
Tuition fees was technically a lie, because all our MPs signed a "pledge" which some of them (more than half) then broke by voting for it or abstaining.
However, other examples are hard to find, because compromising on a manifesto to form a coalition is a legitimate reason to diverge from "what we said" in "what we're doing."
The Guardian did some analysis (which I can't seem to find now) that said something like 60% of our manifesto was being delivered under the coalition. I think that's pretty good going for the smaller partner, and while some of what the government is doing makes me good and angry (DLA 'assessments,' housing benefit changes especially in London, Tuition Fees, scrapping of PCTs, and so on), other bits are much better for it (the Tuition Fees repayment system, the Pupil Premium which was doubled again recently, raising the income tax threshold, the Youth Contract, and so on.)
