Well I have to agree with both Michel and Houston, while I was a bit surprised to see the difference in the menu between 6 and 7. I would like to make the following observations.
1. No we should not "dumb down" Dolphin but working on a site you soon knows where everything is and the same might not be so obvious to a visitor, and since we all want to convert visitors into members, the easier the better.
2. The menu is customizable and while it might require a bit more work, it will differentiate see more a site from another. I regret that some many Dolphin sites are installed "as is" (not even the About us page is changed)
3. Mydattery, I am one of these 40 years old guy you mentioned, I can defend myself versus them 14 years old on building sites, but for the life of me I can't make sense of Myspace.
4. In the past you would see sites with a navbar on the top and the same navbar on the left and on the bottom, things have evolved and to defend D7, several options to reach the page might satisfy a wider range of users. While someone might like to click here someone might look for the link somewhere else
Well remain to be seen, I guess we will know when several D7 are up and running, would be interesting to revisit this blog in a few months
