+1 on forums. Thankfully, we’re on one right now.
Up until the last few years, there were still quite a few independent forums with their own looks, feels, history, etc. Most of the ones i went to got swallowed up by VerticalScope Inc. While i’m grateful to them for keeping the forums going as forum founders got worn out, bored, age out, etc., they consistently nuke what made each of the sites unusual or unique, to shoehorn into their XenForo Fora standardized platform. Yeah sure it’s all well and good for one learning curve across many forums, but it’s a sad loss. For one example, try
a Wayback Machine view of automaticwasher.org vs.
the current site. For another… Dimensions!
Some things that used to be, say Yahoo! Groups are now on groups.io. The Tektronix oscilloscope group is the one i discovered was still alive there.
I miss Usenet Newsgroups. Got off track on those in the early 2000s, having trouble finding a server with the switch from dialup to broadband Internet. So much more sane to have the basic text rather than all the HTML (and later CSS) overhead of a WWW forum.
