Unfortunately, some of the human “guides” who find the search results for visitors to ChaCha are taking a pay cut once again. Last summer, ChaCha implemented a “Pay-For-Performance” system, that forced guides to work five or more hours per week if they want the higher payrate (20 cents per question), which we said would alienate the site’s more casual (but accurate) users. Regular guides would make 10 cents per question. It appears that at some point over the past year, ChaCha lowered the Transcriber rate to 4 cents per question. Now, ChaCha has decided to cut the rates of “Voice Transcriber” guides (people who transcribe voicemail questions and answers) to 3 cents per transaction, with the pay cut taking effect last week.
