two use host
Popularity is the product of two factors: (a) how compelling material you offer, and (b) how easy it is to access it. Host free pirated movies and users will flock to the site, even if it's difficult to use.
loyal-customers giving survival
On the Internet, it's survival of the easiest.... Give users a good experience and they're apt to turn into frequent and loyal customers. But ... it's easy to turn to another supplier in the face of even a minor hiccup. Only if a site is extremely easy to use will anybody bother staying around.

Diversity is power on the Web. Big sites may be bigger, but smaller sites will keep scoring higher for specialized topics, both in terms of their connections with users and in terms of each visit's commercial value.
interesting victory progress
Compared to 1999...we cannot quite declare victory, but we can declare progress.
