Mobile phone numbers

Is it just me or do you not feel safe knowing anyone can get hold of your phone number? If you type your mobile / cell number in google chances are you will find it listed in a directory, creepy!
I get too many phone calls from random "businesses" offering me deals which I don't need, it makes me wonder if this is where they got it from?
Everywhere on the internet seems to ask for your phone number as well these days, I don't know if it's just me but personally I don't feel that comfortable having my phone number exposed to God knows how many people.
Talking of which, random people keep getting hold of my number lately..a bit odd.
Anyone had abnormal experiences with phone numbers on the net?
Discuss :)

Why is it so hard to earn money on the net?

So, a lot of people are lazy, like me! Either that or we have a full time job which doesn't live up to the standards of paying our bills, or we're out of work but want a part time solution.
Working from home can be such a pain, I've been searching things like text chat operators, starting your own business, website making, survey taking, the likes! None of them really seem to pay anything, and most of them say they'll pay and don't, so what's the deal?
If a website is really that bad or "a scam" why is it still on the net? Surely things like this should be illegal.
It's like having an escorting website that doesn't specify that the women or men are being paid for their time and company, that's basically saying that they're selling sex, which in the eyes of the law would be illegal.
Anyway, how have you all found the whole "making money on the net" idea? Tried it? Hated it? Love it? Share your views and opinions, lets see if we can have a nice friendly debate going!
