I'm one of those people that says that if you don't have content for an area, don't display it (or if you do, don't let me dig deep thinking that there is content). The 'Web Development Definitions' appears to be empty. Either remove the link or don't let me go beyond the first page of it (and tell me that's coming - but not with the words "coming soon"). Title of the site is misleading as I'm not seeing a single video
very less content. Put more work on the middle column. Put a nice logo. how can someone expect learn from a badly designed site , so make your site look good first and set an example.
Tutorials are always useful, but design is too simple. If you offer CSS tutorials - show how it works, at least at your front page
Navigation is kind of hard. It would be nice to have "Previous" and "Next" buttons, kind of like on W3Schools.
