Excluding, say, here or the fediverse more broadly.
There have been some nice corners of the internet that have somehow kept going along their way that I’ve enjoyed lurking around like some alien observer. They are the few spaces I dare not pop in and ask, out of fear it would somehow break things.
Geocaching is great! I haven’t done it actively in a while but occasionally I’ll find a cache that someone else must have found and not understood what they had uncovered. I try to find the cache online and then rehide it.
