My youngest daughter loves to get ideas from me for my birthday. She's really into giving and receiving the right presents. So, when she asked me what I wanted I told her I wanted the first-season DVD of Sons of Anarchy. Everyone tells me it's like Hamlet, and I always was a big fan of Shakespeare's work. She texts me back immediately -- we ceased to communicate by actual words a long time ago, but I would recognize her voice if she called -- and writes she isn't going to buy it because it streams on Netflix ( NFLX), so it is a total waste of money. Memo from me to you: Any time, any time whatsoever that a teenager is worried about spending your money, sit up and take notice. My daughter swears by Netflix more than she used to swear by Apple ( AAPL). I should have figured that, After all, the new televisions of even the most dubious quality come with Netflix right on the clicker. Can you believe that? No wonder it added 2 million subs this quarter and rallied huge, especially when you consider that it ruled out doing an equity offering to pay for all of its new content. The shorts wanted to buy that stock on the underwriting dip. Forget about it. My daughter's also the one who told me that she's been buying things off Facebook ( FB) lately, well-timed, right when Zuckerberg came on the conference call and said the company had screwed up mobile but was now getting it right. You might have figured that out from when I went positive on its soon after that conference call. Alas, she is also the one who turned me on to Apple at $50 when she asked for her second iPod because she had a blue one and wanted a pink one as a fashion accessory. Alas, she and her sister are also the reasons why I had to cool on Apple as they simply didn't want any of the new stuff and are still angry about the cord and the map and the new iTunes. Her sister, the other day, wanted to know when you could buy shares in Twitter because she said that could be a sensational buy.
