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.

I would really appreciate it if you took the time to read this and address my problem. 5 stars for the best question NO MATTER HOW LONG that solves my problem. Anyways, I was so happy when I got Call of Duty 4 for the PC. I named my profile “PkedU2Fast” not after runescape, but just for a good name, because runescape fails. I made it to level 13 and decided to take a break from the real game and play a mod. I had dozens of mods downloaded but was bored with them, so I downloaded a new one. It was a zombie mod, and after downloading, it said “An error occurred.” I clicked continue and it took me back to the server screen, I clicked join server and the screen froze and it stopped responding. I tried multiple more times to click join new server and even used the console to try to connect to a direct ip. I came to a conclusion that the mod I downloaded ruined my profile. So, I deleted that profile, made a new profile, and it worked. I was happy as I continued to unlock more guns and rack up more points as I unlocked attachments for them. My name for this profile was “CD|PkedU2Fast” because I had gotten admitted into a clan.I made it up to level 23 and got off. The next day, I started the game as usual and when I clicked join server, it took me to the server list, and I proceeded to click “Favorites.” It was weird at first, I had only 4 favorites instead of the 10 or so I had with CD|PkedU2Fast. I noticed that they were the favorites I had when I was just PkedU2fast. I clicked to join a game and my classes were strange, they were different from CD|PkedU2Fast’s classes. I thought “Ohmigosh! My classes are exactly the same from PkedU2Fast’s classes.” I also noticed that I was level 16. It was very weird, my profile got reverted to a profile that was deleted. I exited CoD4 and opened Computer. I looked in the files, and saw all the data for CD|PkedU2Fast, and no PkedU2Fast anywhere. My computer was accessing PkedU2Fast from a hidden source even though I deleted it. I clicked select profile and only found PkedU2Fast. The next day, everything was back to normal, all my classes and my correct level, and I was CD|PkedU2Fast. About 2 months later, I wasn’t playing extremely frequently, about 3 days per week (but for several hours per day); and I was level 47. One day, I got on and noticed that I was level 16! My classes were different again and my favorites weren’t the same. This time I really thought “Ughhh! !#$!$#%!” My profile was reverted again. And this time, it’s been PkedU2Fast and not CD|PkedU2Fast for over a week! I really don’t want to level up again. All my progress was gone, I also thought about the countless hours I had spent on mods. I got on my friends Zod mod and noticed that my stats were of CD|PkedU2Fast and not PkedU2Fast. So, my mod progress wasn’t gone, but my regular game status was. Please help, I wanna get CD|PkedU2Fast’s stats back, and moy normal game stuff back. Help please.
