Web 2.0 is the new trend for anything and everything in new web sites, particularly the look and feel has to make a significant impact. Of course there is no precise measure, guidelines and parameters to define any website to make a site web 2.0.

Logo of the site is as important as anything else and should be very prominent, having a 3D effect and should show a positive attitude. Now how do we determine that? It is again a feel factor. Here is a fantastic site that displays some of the famous “Corporate Logos redesigned” in Web 2.0 style. This should give a fair idea of the feel factor and a comparison benchmark.
