The thing that stuck with me was that I always had the impression that the Video quality was much worse than on Youtube. IIRC when there was content that was available on both platforms, Youtube had the much better picture and sound. But maybe that was just specific to the content I watched back then. There was not THAT much to see in the beginning, not like today where you can spend 24h straight and always see new stuff :-)
Could be, on my connection back then the quality difference was probably unnoticeable. I remember having to wait for buffering every time I played a video on a website.
