I'm trying to understand your post.
I think a running wish list is a great idea. Maybe one where people could vote for the ones they want implemented first, so you don't just get me-too responses scattered about.
Why don't you want to use a database for dynamic data?
Where are they relying on Wordpress and Blogger?
"why you are putting so many eggs in the CSS basket",
as opposed to what? I think it's sort of important to stay with standards at the time products are produced. Most people are using CSS now so I think it would be a mistake to go against the tide.
Not sure I know what you mean by "I have yet to get the data assist to work on my server". It is used on the desktop not the server. If you are talking about the generated code, you would have to be a little more specific.
"since you are focused on PHP, it seems there are many designers that would pay for a legit coding solution. ",
It sounds like only PHP coders would pay for legit code? Not sure what PHP has to do with it or what a non-legit solution would be. Are you talking about RSS, CSS, or Data Assist?
