Yes. Don't be afraid to post your <i>real</i> URL here. A TinyURL looks unprofessional, shady and gives the impression that you're not quite sure about the success of your startup.
Good start. Here is some feedback:<p>1. What does "Flexible learning environment" mean? I don't think this phrase adds any value.<p>2. "Learn from people you know and trust": Not sure if the people I currently know possess the best knowledge. I've been out of school for a few years.<p>You need to iterate over your landing page copy a bit more. Get some help from friends or classmates.<p>3. The text on the features page (/features) is too verbose. Most people won't read all of it. Make it shorter and to the point. Also, more pictures or screen shots would make it easier to understand.<p>4. The typography of the word "Cafe" in the logo makes it hard to read. Black on dark blue does not provide enough contrast, and the font is too faint to make the logo memorable.
So my advice is to: a. Choose a high contrast color scheme and b. Choose a more prominent font for both words in your logo.<p>The logo also seems to be inconsistent across the pages. For example, it looks different here:
<a href="http://www.cafecourses.com/courses/31-integrating-authlogic-with-rpxnow" rel="nofollow">http://www.cafecourses.com/courses/31-integrating-authlogic-...</a><p>5. The "Feedback" div on the left occludes some of the text on the features page. I realize that I'm on a small laptop with 1024X768<p>6. Hmm. Are these courses or tutorials? "Adding CAPTCHA to your site" sounds like a one page tutorial.<p>7. You need to iterate over the copy in the "About" page. It is hard to follow, and can be structured better. For example: you should encourage people to upmod great content, rather than vote down courses. Especially when most of the content is written by you.<p>Best of luck.
In the interest of full disclosure the site that is linked is <a href="http://www.cafecourses.com" rel="nofollow">http://www.cafecourses.com</a>. I have asked for feedback previously.<p>I would have included the URL in a comment but HN does not even let the original poster add a comment to their URL post until someone ELSE adds a comment for them.
My feedback:<p>Why does the site ask for my photo if I'm using Facebook to login?<p>There's a lot of text after I finish registering. I think it's confusing.
