I read a blog post at A Library By Any Other Name about Apture. Look for the Apture links that were created for Texas, Chihuahua, and Oatmail Raisin Cookies. Texas and Chihuahua have a W enclosed by a box in front of the underlined word, which stands for a Wikipedia entry. Cookies has a camera, which stands for a picture.
When you go to http://apture.com you will see a demo of Apture without sound. Submit your email and complete the signup process. You will receive an email from Apture that you'll have to click on the link that is sent to confirm your registration. OR if you go to http://apture.com/experience, you will see across the top of the page three choices: About Apture, Experience Apture, and Add Apture to your Website. Click on Add Apture to your website. If you haven't signed up yet, the signup process will appear.
If you have created an account, Sign In. The first thing you have to do is add a new site. This would be your website or blog. Click on the link and enter the name and url. Just follow the rest of the steps to configure and install Apture. Once you have gone thru this process, I think that I got a tutorial that I could go thru with a basic explanation of how Apture works.
You have to complete an entry first. Then you go back and insert the Apture links by highlighting a term, name, whatever. A popup window will appear with various choices for the type of links available. To add the Apture links you just need to be viewing your website or blog. I don't think that you even need to be signed in to your blog account, but you do have to be signed into Apture.
There is an Apture dashboard that appears when you press the "e" key. You can sign in from the dashboard. I haven't needed to go back to the main apture site.
Once you get past the installation and tutorial I don't think that you'll have any problems figuring out how to use Apture. You'll find a wiki with documentation about using Apture, if you want to read more here. And of course, checkout Apture's blog.
Apture is a great tool for making your blog or website a multimedia experience! Not just Wikipedia or pictures, but also sound and video. I love it.
