At the end of the day though, the engagement just wasn't there. You would go on there a few times, check out a couple of bags, maybe create one or two and then never come back. It's sad it didn't work out but the founders are all insanely talented people and I'm sure whatever they go on to do next, it will also be awesome.
Pinterest on the other hand took me a mere 10seconds to figure out what it was and how enthusiastically I wanted to use it.
I got tired of saving pictures of the products and architectures I liked. I was searching but I don't remember how I came across Pinterest, but when I did, I had to get in. It was early in their beta, so I sent off an email to Ben and said if you want a loyal user, let me in right now.. and he did. It was exactly what I needed!
I've been collecting all the gems of the industrial design world ever since. I even got my mom registered so she can find inspiration for her home renovation.
It's very visually appealing. None stop inspiration.
Then sites started requiring emails to sign up - and you signed up anyway. Why wouldn't sites just let you register through snail mail? They're limiting their user base!
In all seriousness, Twitter and Facebook are trending, and you might as well adopt them. Not doing so would strike me as a bit of technological ignorance.
Note: I have accounts on these sites and actively use them, just my guess as to other peoples' rationale behind not getting an account.
