I by far prefer paid to post too. As a teacher and writer, PTPs (or PTWs) give me the possibility to get paid for my e-books (published chapter by chapter), musical video slides and tutorials, free of the stressful traditional path concerning publishing houses. And I also like paid to post forums. About survey panels, I only choose those with the disposition to pay for partial completion and even disqualification (Theorem Reach, TapResearch and in-Brain, to be specific). The rest of the survey panels are a waste of time for me, as I live in a tier3 country as many of you.
