I've had a PayPal account for a few years now, but I've never used it. Today an editor in the U.K. paid for a short story via my PayPal account. The process--especially because it involves converting payment from one currency to another--was much simpler and faster than my other method of dealing with payments from other countries. There's no filling out forms at the credit union--forms that only one person knows how to find and no one knows how to complete--and waiting for several weeks for money to appear in my account--minus a severe service charge.
I guess this means I've made another step into the future. At this rate I ought to have a cell phone before the turn of the century.
