It's quite convenient when you can shorten your URL and earn a little money to share your link. Tinypaste has a very nice interface and that won’t annoy your audience much. For a thousand unique clicks, you will get $0.5. It seems to be a small amount but if you have a large number of link for download, that counts. But I’ve seen some one has several hundred files and he posted to a heavy traffic forums and each link get few thousands click per day. So that in principle you can get hundred bucks a day if you try hard enough.
And what’s else, it paid in Paypal, which is extremely popular right now.
