Sure, the spoken lesson is: be careful what you share, there are risks.
But the article isn't about privacy conscientiousness, it's about brand conscientiousness.
The author isn't talking about how she might construct rules to effect a safe space for her daughter to grow and learn and internalize these values, separate from known pitfalls that might cause her harm.
The author talks only about how she constructed a safe space for her daughter's brand, separate from whatever might befall her daughter while she's maturing.
It's might seem like a minor distinction, but it doesn't feel that way to me. It makes the whole article feel essentially disingenuous.
The idea is to get out ahead of all the social networking bits, and create a deliberately blank slate. All of that stuff is placeholder, neutral, for as long as the kid wants it to be so. The kid's free to fill all that in, or not, but the child won't start with a bunch of their personal data filled in. That last part is consistent with the stated beliefs/goals of the author, bearing in mind that over time data only accretes and there's no undo.
'Desirable' usernames are, technically speaking, as close to irrelevant to privacy as you can get. Your behavior with an account is what matters for privacy, not the account name. [1]
Yet the article is entirely about the account names and only somewhat in passing about the sorts of lessons the author hopes her daughter learns about "how (not) to conduct yourself online".
And without those lessons... you can 'protect' facebook.com/janeannsmith all you want, but if your daughter makes privacy-eroding mistakes with reddit.com/u/sparklepony2031 -- those can be trivially connected to facebook.com/janeannsmith the second you hand over the 'keys' to that account.
That's the whole point about the loss of privacy online. Once the accounts are associated to you, those associations last forever and follow you immediately and irrevocably anywhere else an account becomes associated to you.
[1] sure, sure -- using your real name as a username is Bad For Privacy, but the author wasn't talking about janeannsmith vs sparklepony2031. They were talking about janeannsmith vs jane-ann-smith and janeannsmith vs janineannsmith -- should jane ann smith have turned out to be the name of a porn star or third world dictator or some such.
Frankly, as far as privacy goes via name conflicts, you're better off being named Mike Johnson and having lots of collisions, even if some are negative, than having some unique name that doesn't have an online association yet. Some plausible deniability is better than none.
However, for branding, the opposite is true. Which, again, underscores how the author's behavior seems to be much more about branding than privacy.
Yes, thank you. That's an excellent way to put the same problem I had with this article. The first half is "we're protecting her privacy", and the second half is "we're building a brand identity which will deny her any anonymity".
From the article: "And to this day, we’ve never posted any content." They haven't built a brand (or denied her anonymity), just the empty space should she decide herself to build it.
The point may also be to make sure that someone else doesn't make that decision for their child. That is to say, to make sure that some kid in their class doesn't decide to grab the name so that they can set up a fake profile for their daughter...
(Personally my wife and I have no information on our kids online, save a self-hosted blog with a password that only family know...).
