I am using this site for 5 months or so and Twoo.com has improved a lot since. The free experience is annoying as you never know which link will invoke a payment page. After seeing them too much, and still using the service, you pay (I started 2 weeks ago- i know i'm too soft for this). I really love the site and especially the people on this site. Have been travelling a lot and you don't get the same kind of people in each country (at all). Also use the mobile version on my Android phone and works really well.
