In the freelance writing gigs, it appears about.com is gone (gasp!) it links to a site called dotdash.com. I tried going to about.com myself to make sure it wasn’t a bad link and sure enough it took me to dotdash.com. In their careers section they are currently hiring some freelance (contract) tech writers but that was the only “freelance”/contract position(s) they have. Thought you’d like to know.
Slice the Pie is a site I use quite frequently. All you do is listen to music and rate/review it. You'll get paid anywhere from six to seven cents up to sometimes seventeen cents per song you review just depending on if they have any promos going on. It only takes a few minutes to review a song. They pay out on Tuesdays and Fridays and you must have a minimum of $10 to withdraw your earnings, but this is very possible to do twice per week.
