Valid point that. In 'Encounter at Farpoint', Riker seemed a bit taken aback at the holodeck when he enters it to look for Data. Almost like he was thinking, "Well, I've seen the pre-release reports on how this stuff works, but... wow..."
Having the holo-technology so new would go some way to explaining why it was forever going on the "safeties off-line, we're now in mortal danger" malfunction route. Though it'd beg the question why they'd keep using the system after so many potentially-fatal glitches crop up...
