Some Interactivity Examples

Control:
Blogger: http://www.blogger.com/edit-profile.g

This is my blog's site when I click on edit. This zone gives me the option of changing some information. I haven't found any website in which the user can make changes without register himself; In this one, you have to be registered to make changes. Anyway, without register, before you start doing it, you can, for example, change language.

Youtube: http://www.youtube.com/watch?v=T6tK1iAzI1I

This is a music video taken from Youtube. When you click on the URL, the video starts playing, but you can see that it's loading while it's playing. This is showed by the red line in playing bar. When the circle of "play" reaches the red bar, you have to wait to keep on watching, because it's still loading. This is showed you with a lighting circle in movement: http://googlified.com/files/youtube-video-player-loading.png

Productivity
Song Lyrics: http://www.songlyrics.com/queen/bohemian-raphsody-lyrics/

This is something I usually use. It's a page in which you can look for song's lyrics and understand what all those fast songs say. In other pages, you can find the same song in different versions, in different languages, for example.

Creativity
South Park Studio: http://www.sp-studio.de/

This is a website in which you can create your own funny pictures like the characters of South Park. It's as fun as useless, but it's a good way for loosing your time ;).

Adaptivity
Youtube: http://www.youtube.com/?gl=ES&hl=es

Now you'll have to do something. This is Youtube's home page. When you start typing, the page itself tries to help you by suggesting you some possible searches. For example: Start writing "i"-"r" and the first option will be Iron Maiden, then Iron Man, Iris... and more results.

Communication
Bateristas (Forum): http://www.bateristas.net/foro/forumdisplay.php?f=5

This is the forum of the website "bateristas.net". Here I can look for information about drums, taken from other drummers like me, and then chat with them to ask them for more questions.
