I’m quite tempted by fed.brid.gy (turning your indieweb site into a first class citizen of the fediverse, basically become your own instance), but I really like being part of the #socialcoop instance. I only really actively look at the local timeline (and passively I see a bunch of interesting stuff from elsewhere that gets boosted). Would be a shame to lose that.
I actually really like the idea of digital personal assistants. Sometimes a timely digital reminder can stop my lizard brain from putting the kibosh on my frontal lobe. The problem, as with most things, is that they’ve been hijacked by commercial interests, who wish to harvest your attention, not support your intention.
Browser plugin idea: something like those (admittedly annoying) anti-virus browser extensions that tell you if a search result is ‘safe’, but it tells you whether the organisation behind a particular result is safe for humanity or not.
