I miss Server Fault-- more the time in my life, I suppose, than the site itself.

I enjoyed the hell out of answering questions on Server Fault for a few years. It came along around the time my teaching gig at the local community college transitioned to online-only classes (which, oddly enough, I couldn't find enthusiasm to teach). I feel like the Server Fault community tried to make it a more hospitable place than Stack Overflow, FWIW, back in the day.

When Stack Exchange added the realtime chat system I got into interacting with members of the community more than could be done in questions or comments. There were even a couple people who ended up being IRL acquaintances. There were also wacky hijinks, too: https://meta.serverfault.com/a/1854 (I'm agog that those things happened 15 years ago, too... Yikes!)

Then we had our daughter and my time to dedicate to the site became scarce. I knew it was in the cards for me to lose the top spot on the leaderboard so I decided to just pack it in and quit cold turkey. I think I'm still fairly high on the leaderboard but, other than occasionally getting search engine results that point me to the site, I've stayed away. I don't live there anymore, as it were.

Edit: My favorite part of the site was having friends and Customers tell me about times they'd search-engined a question and found themselves using one of my answers to solve their problem. At least one Customer was amused to discover I'd fictionalized their particular situation as an example in an answer.

Tons of fun. Yep-- I miss that community.
