Whats the preferrable way to make money online???

You try all these jobs and evaluate yourself. Because the interest vary person to person.My interest may not matching to yours. After doing all these you will come to know what is the job suitable for you. Good luck.

I take surveys online for cash, and usually end up around 200 a month. Albeit right now I have time to take every one I can, as I don't have a job. That changes in 2 weeks, which means I will be making much less taking surveys, and only doing the ones that offer the most.

Check out my blog in my profile. I have a list of sites where I earn money online.

All you specified are good income generators. The trick is finding the best site for each. Remember they are popular because they all help. Problem is, scams invades all means of income, outnumbering the legit ones. Don't just take anybody's word of how good a site is. Do research and get the general responses of users. If it's somethin' new I'd stay away. Let them produce proofs of payment recieved not one but atleast 3 in a good span of time. Scam sites ussualy offer above market gains. Just be careful and you'd be fine.
