Nevertheless, this is the twenty-first century and I will try to keep up (to some extent), primarily for the benefit of my descendants, some of whom seem to actually care about what's going on with me. So here are the places you might find me:
E-mail to firstname.lastname@example.org is still the best way to find me. I keep a couple of backup e-mail accounts at ProtonMail (for more secure messages), and at Vivaldi.net because it is helpful to have an alternative as a backup or as an additional contact point for account verification (like when you're locked out of an account and you need some other way to communicate with the admins). The two backup accounts are only checked occasionally (when I'm testing and updating my security details).
Don't look for me on Facebook Messenger or whatever the current rage is. I sometimes hang out in IRC chat rooms (see Freenode for an example, if you aren't familiar with this old-fashioned form of text messaging), mostly in connection with a particular topic of interest to me.
If "text messaging" means SMS/MMS cell-phone text messages to you then the app I use for that sort of thing is Signal, offering secure encrypted transfers of text, voice, video, document, and picture messages to individuals or groups. You might also find me on Telegram as @jdcard, but Signal is my preferred choice.
POTS (plain old telephone service) is still king of the hill here. Yes, we still have a "land line" at our house -- well, it's actually VOIP from Voipo running on our CenturyLink fiber connection -- and we have our cell phones (see Ting for a good deal) that we use when we're not at home. For video, I still have Skype installed though I've never actually used it beyond a couple of test calls; I prefer Whereby for video chat now, and no, I don't think Zoom is a good choice.
I deleted my LinkedIn account after Microsoft bought the company -- besides, I'm retired now and don't need to maintain that set of connections any longer. But I have given in and joined two other social media sites: I find Nextdoor useful for local connections, and MeWe for the time-wasting perpetual scrolling of timelines and personal feeds. If you've ever hoped to find me on Facebook, this is as close as I'm ever likely to get.
Oh! I almost forgot that I joined WT.social, which is something like Reddit, as near as I can tell. And, I am @jdcard at the social.vivaldi.net and the social.linux.pizza Mastodon servers.
At least the choices I've listed above come closer — I believe — to respecting our rights to privacy and control over our personal data; though none of them are perfect.
