My personal favorite are currently "Bill Gates is a great guy", and "Microsoft loves open source". They have been fantastically orchestrated for the last few years in regular medias, but also on sites like HN, reddit or even imgur (!).

And it worked very, very well. The pro BG and MS sentiment is growing more and more every day, while 15 years ago, they were evil.

Partly because the communication was amazingly good, smart, and on the long run. Partly because they Gates and Big M did do good things in the mix to support the narrative, and so it looks very real.

It's nicely done, you'll notice a few posts here and there, but the real work is done in the comment, like gardening.
