My opinion - I use it but really just as a vehicle for hosting my client models. I would much rather host them myself, but that is currently not an option. The built in viewer is horrible, IMO, which is why I tell my clients to NOT view it there, rather click on the SketchUp icon to open in SketchUp browser. It is probably like most things - you have to use it and learn it before giving up on it, I just have not had that kind of time. I am currently working on a 6-story condo building in Canada -now that might be a good opportunity to test integration with other software users (like Revit). I am looking into this now.
