Believe me or not, but I LOATHE Facebook and have blocked it; the website and also their several tracking tools / techniques where and how I can able to. Disclaimer: I still have an account in another small social network, but here European data privacy laws apply. Not being active there that much anymore. I don't wanna see people's stupid chitchat, what they ate, what photos they took during vacation, and especially their even more stupid flash games requests/status messages. So back to email and phone. And I was very vocal that if somebody uses their and my email address to send me an invitation or something related to FB, I will block those too. My privacy is much more valuable than some perceived easyness of communication and "fun". I now even poke fun of some people for showing stupid and careless behavior regarding the web and companies / things "that do you good".

Regarding hotspot connectivity, I was not able to use MobileHotspot on the N900 with a GalaxyTab 10.1 too. And check your PreCentral link, it seems its a not-too-seldom issue for tablets. Anyway, Advanced Browser is ok, nothing special, but was just recently updated to open tabs in background. We are slowly getting there... And I can read eBooks in a good way with the Kindle application and sideloading. Quell HD and Jigsaw Master are addictive too...
