In the first few lessons I learned and practised what to do with my thumbs and ring fingers. The site is cartoony and there's sound too. After you build your lessons you can generate progress charts. The traditional search engines are great for key words and now there is a new generation of search facilities. Webtop is one of them.
Searches are now 'concept driven'.
You no longer need to type your search. It's replaced typing with a simple drag and drop action. And in so doing has brought more context to what you're looking for. Try it out. If you like traditional searching methods on the 1 billion web pages out there, but can use some fine tuning, check out this site.
