> It seems like reviews are driven by people who don't know, and respond reviews by to people who don't know who describe what sounds like fundamentally broken things... so they give it a thumbs up and they're both completely ignorant

Heh. One of Google's featured reviews for ZXing is a one star review from someone who said they started getting popup ads, and looked up the issue on a web forum which said it was ZXing's fault. It has 30+ thumbs up.

Absolutely pathetic.
