What these opportunities typically turn up to be is a pyramid scheme. You pay a fee to signup. You then receive a flyer saying how great stuffing envelopes is and list of names and addresses to mail said flyer. IF those people pay that signup fee so they can mail that flyer too, you get paid a small referral fee. ONLY if they take the bait do you get paid.
Also, why no mention of a site like Demand Media? My wife writes for them and most of the articles pay $15 a pop. Once you get used to writing for them, an article shouldn’t take more than 40 minutes to research and write. And if you possess some knowledge in really specific, technical areas the payout is larger. Again, with the google algo change, not sure what is in store for the site, but supposedly eHow has benefited and Demand owns eHow.
If you're crafty, you should consider selling your stuff on Etsy. Etsy is designed for handmade goods – including stationary, greeting cards, household crafts, and more. The great thing about creating these types of products is that you can do it in your spare time, on nights and weekends. And creating many of these products doesn't take up much space – so it can be dorm room friendly. Don't think there's much money in selling on Etsy? Well, this teenager paid for her college by selling crafts online.
The revenue sharing aspect of do-follow sites like InfoBarrel really is awesome when you think about it. When I find a long-tail keyword that I like, but that I don’t think has quite enough traffic or high enough CPC to make it worth doing a whole niche website, I can still utilize it by writing up a quick 500-word article, and I can add a simple signature pointing toward my main blog.

Whether you have a website or are still dreaming up ideas for a blog, you can also look into affiliate marketing. With affiliate marketing, you partner with brands and businesses within the content of your website. If you mention a product or service, you link to that produce or service using a unique affiliate code you received when you signed up for that particular affiliate program. From there, you’ll make money any time someone buys a product or service through your link.
