This seems like a very similar service to the wildly popular Instapaper. I'm curious what the difference is or how Copyto plans to differentiate themselves.
Man, I always get the same observation with historio.us as well. How are they similar? Instapaper saves links for later, historious saves the full content of bookmarks and allows you to perform full text search on it. They're nothing alike.
I guess the difference might be the tools they provide to drag and select parts of pages and only save them to read later
