Instapaper is a new site that does one simple thing: it lets you save a URL to read later.
I still love del.icio.us for permanent bookmarks, but Instapaper is much simpler. No tags or description — simply use the Read Later bookmarklet to save the page. You can then go back to your Instapaper page to see the list of URLs you saved.
It’s so simple you don’t even create an account. Just enter your email address or make up a user name. It doesn’t even require a password, although you can set one if you prefer.
It can even be used for simple collaboration. If a few people use the same name, they can send pages to each other.
