Do people still use this site?

Yes, there are still users here from 2+ years ago.
This place ain't as active as it used to be though.
But fanpop is supposed to be getting a site upgrade though, so there's that to be aware of.

I left this site for 3 years, and came back a few months ago.

It's like a barren wasteland now.

I've been here since about '08 and I've seen a lot of users come and go. There aren't many, but there are still a few users around from the '08 era.

Mostly 13 năm olds.

this is my first năm here. in August, i am getting a new account (might), and i will not be here in the summer. so i do not know how long people were on here on fanpop.

Yes, There Are Still People Who Use This Site And Not Just 13 năm Olds. Although It's Not Like It Used To Be. There Is Far Less Activity Than In The Past -_- !!!!

I'm relatively new here but from what I know there used to be much thêm activity on this site in the past...

Ya people still use this site. I am a user from 2011. Like other people have đã đưa ý kiến users come and go but people generally still use this site and it's not just only 13yr olds.

I've been here since 09. A lot of older users are gone, but the site is still relatively active. Ish.
I wouldn't say it's mostly 13 năm olds, but probably in the range of 15-17 with a few outliers.
Not in the way it used to be, though. It's pretty dry compared to before.
But hopefully new features may bring a much needed breath of life here.

The old users still exist, but there aren't very many of us here anymore. :\

Haha, I took a hiatus about that long too. But, even though it isn't super active, I have found some new Những người bạn here.
