It appears many people in this thread find this interesting (particularly in the ways technology interacts with stalking) so it is on topic.
Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic.
I find this article to be in the "crime without any interesting new perspective" category, since the phenomenon of Internet stalking is old news by now, even for mainstream media.
Then again, lots of politics and crime stories seem to be making their way to the front page nowadays and there's no way to vote against them except to flag. So maybe I should just hope we at least stay clear of sports articles, or switch news sources ;).
I think it's reasonably on topic.
1) Startups (some anyway) tend to get a lot of media attention
2) Startups have fragile reputations while they are making a name for themselves
3) Startups tend to have more personal relationships with their customers than more established companies
It follows that startup personalities will encounter stalkers of various sorts. Articles about a potential consequence of this, discussions of how to deal with it and so on seem as on topic as "tips for personal productivity", "how to deal with office politics", "Prosecutorial overzealousness", "copyright" and other recurring themes here.
Further, speaking a bit more generally: People here are pretty prone to living huge amounts of their lives online. One of the dark sides of the internet is that it has been a great stalking enabler, and those of us who spend a lot of time online in forums, etc, can be at greater risk for general muck-raking, since the volume of stuff known about us "on the internet" is larger.
