(Empirically) statistically, though, the 50+ age group is significantly less up-to-date with internet fads than the below-50 group. Yes, there are exceptions, but a quick glance will inform anyone of the same comparison.
That said, early-20s here, and I'm turning off Buzz. I'm also out of FB. Which makes me one of the oddballs for my age group.
First, I do not have the statistics, though now I have supporting statistics. Such a claim cannot be accurately quantified, so not only can I not ever have such statistics, I only claimed that it could be discovered empirically - essentially, by looking at what is, instead of requiring hard fact.
Fastest growth implies nothing without a scale to start with. If there's one 100+ year old on Facebook, and in a single day two more get added, they've got a projected growth rate of over 70,000% per year. Skewed and unmaintainable statistics are effectively worthless.
Look further down the page, especially at the pie chart showing FB use by age group. 45+ amounts to 8% of users (55+ only 3%). The 18-25 group, which I'm in, amounts to 43% single-handedly.
The 45+ group is growing faster than others because they're years behind everyone else, and typically fewer join at all than the earlier adopters. QED.
