Affiliate Marketing Secrets

“When Facebook launched, social networking was not mainstream. Now, with popular competition like Twitter, Google+ and LinkedIn, along with dozens of niche networks and MySpace lurking on the horizon, users have other choices. If Facebook was free forever, the resulting concerns about data and privacy begs the questions – would users really stay?”
I’m from Japan.
I don’t understand what the last sentence in the text above means, among others,
“beg the questions” and ” would user really stay?”.
Could anyone kindly paraphrase or clarify them?
I’ll appreciate your help.

For example, facebook and Twitter are used for social networking, YouTube for videos.. So what kind of niche which isn’t fully exploited today would boom, in say 5 years time?
BQ: websites you visit most often, along with age, nationality and gender.

As Fox News noted in its own coverage of the incident, the network had earlier been covering a story about another apparent Secret Service social networking-related gaffe: Its visit to a 13-year-old Tacoma, Wash., resident at his school, where agents interrogated the boy without his mother present. His infraction? Warning on Facebook that the president should be vigilant against possible terrorist attacks in the aftermath of Osama bin Laden’s death.
Timi Robertson, the boy’s mother, told local Fox affiliate Q13 that she “just about lost it,” when a school security guard called her to inform her that her son was being interrogated. “My 13-year-old son is supposed to be safe and secure in his classroom, and he’s being interrogated without my knowledge or consent privately.”
