Thanks for the feedback and the link! To answer your questions: 1) "I wonder what does it mean by "customizable"" You can add different plugins (that produce answers) and control when to activate them. You can also create mini-search engines that search specific domains. There are also a few settings about security that you can tweak. 2) "how is this different from DuckDuckGo with its duck.co" This search engine also includes a feed reader and get results from your feeds when you search. Also, the plugin system allows you to add data and plugins (written in 100% Javascript) instantly without anyone's approval. 3) "Why I should register for an account?" Since this includes a feed reader, you need to create an account to save your chosen feeds. Also by creating an account you can create your own mini-search engines and add plugins other than the default.

Since you've asked these questions, it's clear to me that I haven't done a good job explaining these things on my site. I'll be working on improving this. Thanks a lot for the feedback!
