- whereas nearly every person I know under 30 has an online dating site account (or three) or uses social networking sites as a de-facto dating pool. They use clubs too, but less for finding people, more for going out with friends. For myself, I use online approaches to filter out obvious incompatibilities which you can't see in advance, in-person... but most of those I've connected to at-length I've known first in real-life. Initial conversations tend to have the same filtering function.
Your experience of younger adults and what scenes they run in doesn't match my experience of them at all.
Some statistics here http://www.webpersonalsonline.com/demographics_online_dating.html
show that eHarmony has this sort of mean (average, not median) age of mid-40's... but most other sites trend a lot younger, Match.com and Yahoo Personals in particular. OKCupid isn't mentioned in these demographics, but the data they published in their now-defunct but awesome data-nerd's heaven of a blog was median of about 27.
It's worth noting that older online-daters are a growing trend... I just think the data on this infographic is misleading. And comments like "Older adults are less willing to run the dating scene that younger adults use." feels like classic confirmation bias. And not confirmed in the data. Considering that participating in online community of any kind is something that an older demographic is only starting to come to in the last few years (through tech-savvy folk getting older, and online community becoming more main-stream), I think it's not surprising.
