I love your product, I was thinking about writing my own WP extension just yesterday. I was happy to see in the FAQ that you are working on having the users own content come up.
There should be a preference to have a users own content come up first. As you probably know, linking to ones past posts helps to increase hits (more ads loaded) and keeps a visitor on your site longer. If theres a preference to enable or disable this preference that would be nice.
Also I don't understand why when a company name is typed a link to wikipedia is suggested instead of to that company's official site. Wikipedia is usually linked to reference something like a concept, a historial reference or sometimes a person. Like today I sent a link to my friend on Wikipedia about.mobi. So if you could have a preference where it uses official sites instead of wikipedia entries that would be good.
You definitely have to enhance the images feature, There should be a more icon or button to view the next 9 images or something, Not satisfied with this. If your concern is too much loading time, having a button would solve that, it would only affect those who want to see more image results.
If you like my suggestions, hire me! Where are you guys located?
