I think this is pretty accurate. My reunion this year had a pretty weak turnout as well. I flew across the country for it, but some of my friends who still lived in town didn't even come. We had maybe 25 out of 300. Kinda disappointing.

This is most of the reason I stay far away from the Facebooks -- because all those people I never had any interest in keeping up with have made it into one long, neverending high school reunion. Ugh.

I really hated high school...why would I want to go back to there?

I hated HS, but really liked many of my classmates.
It was nice to see them at the reunion, but I did have to throw back a couple drinks beforehand.
(and through-out)
Strange how the childhood insecurities you think you've long gotten over resurface in your mind though at times.

I love it!
I occasionally feel the urge to see large groups of people I went to high school with, but not that often. I honestly find the idea of going often - and the people that never grew past HS - rather repulsive.
But I've joined various hometown/special interest FB groups that have satisfied/exhausted any curiosity I've felt about any of my classmates (other than the one's I've chosen to remain close to). It's nice to have that sense of detachment that social media allows. It's like tapping the glass of an ant farm.
For me, it's more slightly less horrible thing replaces horrible thing.

Grow up grownman.
If there is much to this thing about FB replacing reunions, then I would bet much of it is generational too. And thus changing.

I've moved on from HS and am not one to look back on it much. I use a different name on social media to keep the pre-20s dross off my friends list.

FB made me realize that I never want to see the majority of my classmates again. It's also painfully evident that most of them stopped learning freshman year.

I was totally going to fly to Miami and pay $100+ to hang out with a bunch of people I hated at a horrible South Beach nightclub.
