Press This provides a lightning-fast way to grab text, images, or video from any website and post it to your blog without ever visiting WordPress.com. You can also use Press This to quickly share a link on your blog.
It only takes a second to get the Press This mini-application going. Simply go to Tools -> Available Tools in your dashboard and find the link to the bookmarklet:
I just went in search of a bookmarklet to post snip-its of interesting content to my wordpress blog. I know Posterous has this, and I wanted to duplicate that ease of posting. I discovered the answer in Press This which is built in to wordpress already. What is more, I had forgotten that I already have that bookmarklet in my bookmark toolbar. So I am posting this link for Press This with Press This. Ha.
