"people just aren't interested in the guy" isn't accurate - "people who use social media aren't interested in the guy" is. The candidates with low numbers on social media seem to also be the candidates whose supporters are less likely to be on social media.
I acknowledge that this is an imperfect, perhaps fatally flawed, metric - I'm sure it skews young, for example. Something I noticed after posting is that Rand Paul isn't on the linked list (and is barely holding on in polls), but has 2 million FB follows. But who knows, I could see him picking up as the fields starts winnowing.
But I think it's fair to characterize Jeb's numbers as indicative of low interest. There are a ton of people on Facebook in demographics that Jeb needs to do well in to win. To stereotype (using known statistics), white males in their 30's tend to vote Republican - there are plenty of those on Facebook and I see them "sharing" conservative links every day (and I can see that many have followed guys like Carson and Paul). In our increasingly "filter bubbled" world, I think we're seeing people aggressively tune out milquetoast establishment types (on the right at least).
"We never waged war against Microsoft over IE7, we simply wanted people to upgrade their web browsers..."
Maybe so, but the splash says "Use a better browser" and lists Chrome, Firefox, Safari, and Opera. It would be ridiculous for Microsoft to remove the page from their search results because of this, but at just a glance, and maybe to the untrained user, it could look like the are waging war on IE as a whole, and not just trying to get users to "simply upgrade their browsers."
IIRC, XP will only ever go as high as IE7 or IE8. Vista will only go as high as IE9. Anyone hanging around on those operating systems, will need to look outside of Microsoft for a more up-to-date browser.
That true. They could've simply linked to the IE9 download page.
But I think MS's algorithm would have de-ranked the site because any IR algorithm considers the content of the page too - if the web page served to IE users is about redirecting to browser download pages, their crawler (which may identify itself as IE) might not consider it to be the best result about 'Kogan'.
