I've been using
myLot for about a year now, on and off.

It's a great place to go if you want to talk to loads of interesting people who certainly have a lot to say!
Of course there are the odd few trolls about, the same as with any social networking site, but it's unbelievable how efficiently the user community bands together to get rid of them.
There are also people who join simply to add hundreds of friends and post one-line responses to thousands of discussions. The myLot admin soon catch on to this though and ban spammers very quickly.
By posting interesting discussions and useful responses to others' discussions on
myLot you can earn money as well as great friendships. The amounts are tiny at first, but if you have the right attitude to the site then you'll soon see the money coming in. They pay via PayPal, on or before the 15th of every month.
The most important thing to remember is that
myLot favours quality over quantity. It would be more profitable for you to post a couple of detailed discussions and five or six useful responses to others' discussions than it would to go mad and post 100 useless, one-liner discussions and responses. As I've mentioned,
myLot acts quickly when weeding out spammers.
You should also try to get some referrals as you will earn a percentage of everything they earn (I think it's 25%). I don't have any because I've been lazy about it, but I know it would be very beneficial for me to get some!
Finally, all I can say is
please don't post anything until you've read the
Terms of Use, the
FAQ and the
Guidelines. They contain all the rules you need to keep to, such as
not posting referral links in discussions. If you post a discussion that breaks the rules then it will get deleted pretty quickly.
After all that seriousness, you probably need to relax... so go ahead!
Sign up, get posting and have a great time!
**March 2011 Edit I still love myLot and have recently returned there after a bit of a break! It's well worth it for anyone to have a look and sign up to myLot, trust me ;)**
