I perhaps use it in a different way - I more likely use it as a method of suggesting movies I might have never have discovered. I've seen so many foreign and independent movies of late that are REALLY good (and some which are admittedly really average to dreadful) - but the point is, I'd never have looked for them if not for the suggestion service.

I don't believe Netflix has porn - and I may be an odd one out here, but I think that is a GOOD thing. If you want to get that sort of fix, there are plenty of other services to cater for that on the internet. It's not exactly something that needs a recommendation service either.

My only qualm with the Netflix service is for a "tabular" view for browsing titles. Sometimes, scrolling to the right or left can be incredibly annoying. Also, ideally they'd move away from Silverlight, but in saying that it does seem to work for me (I'm using a Mac rather than Linux however).
