I'll miss it as well - my Twitter home feed is already deteriorating. It's been feeding me a mix of football, science, covid/vaccine, NHS, cute cats, data visualisation, economics, Brexit, artwork and whatever TV series I'm currently obsessed with for the past couple of years.
In amongst the dross there's been a lot of good stuff and some fascinating collaborations/interactions between people working in different fields.
For the cafe, I suspect that embedding may well be one of the next things that they turn off in the name of driving traffic to the main feed where the ads are. I already think embedding is going slow - but that might just be a coincidence, as there are a lot of things that affect that.
