That's actually where I first used my username. It was dec0dedab0de.local And the server had the same mac address, which I thought was fun. It's been over a decade now, but I used a locally hosted media wiki instance, and had some bash/python scripts running on a cron to scrape various sources and update the wiki.

I wouldn't do it like that now, but the ability to quickly make wiki style edits is very useful. Plus having data stored locally before you need it is very convenient, and comes in handy during the occasional outage.
