Basically Triond is a place to publish any kind of writing, picture, video, or audio. They have a network they publish the content to the most relevant websites. They split the earning in half with you. They pay by Paypal, check, or Western Union.
Overall the site is good place to publish, but I personal feel that writing will usually earn better on the other sites. However, Triond is a good place for video, audio, and pictures. Triond does allow users to intergrade their google adsense accounts to earn even more.
I have been paid from triond many times into my paypal account; so they really do pay. You can find more information on personal experiences about triond Here.
