the problem is not to know all these details but to "think to know"... they all think it is better to apply this and that, but they do not know, so they make errors... they think they know because some moronish apps are delivered to them to help them create their personal site (i mean, hum, *caugh* framers) and they apply it to their real good software... -- i even had some fights with clients who were soooooo informed of the web that they were asking to revert their site to a 1998 design because of Web2.0 ... because they know Web 2.0, they know all of it...

but they know nothing.
