I'm always happy if i get one reply ! Got to remember there are thousands on here . Not sure of the exact number of members actually , would be interesting to know.
There is a page on Wikipedia dedicated to this topic:External Link/Members OnlyIt applies to all sites, especially sites like YouTube and TripAdvisor, the overwhelmingly majority do not leave hotel reviews or upload videos on those sites yet use them regularly.This site is now getting 900,000+ unique visitors per month (yes nearly 1 million), it's actually a good thing not all of them post. Imagine the mayhem if they did.
