I tend to use floating or fullscreen for general browsing but often you have to type something while frequently referring back to something else - for example when programming I will be looking at the documentation. Or maybe debugging something on the command line while looking at your code to see what’s going on. In those circumstances tilling is perfect.
Proton and Tutanota are the most privacy-focused ones, offering zero-access encryption. The flipside is that they are a bit more expensive and less easy to use with third party email clients.
There are a number of alternatives like mailbox.org, Posteo and Fastmail which are cheaper, and less private than the above two but arguably still better for privacy than Gmail (in that their whole business model isn’t built off capturing and monetising your data).
Personally I use mailbox.org and have no complaints. I use it with third party clients like Thunderbird for desktop and FairEmail for Android so can’t speak to how good their web UI is.
I also strongly recommend getting your own domain name to use with your email. It means if you ever want to switch providers in future you won’t need to change your email address.
They have since announced that it will be capped at 0.1% of a bank’s assets: https://edition.cnn.com/2023/08/09/business/italy-bank-windfall-tax-change/index.html
Google Maps is the last Google thing I rely really heavily on. I would love to be able to replace it with OSM but searching for places is far better on Google (admittedly, probably because they have more context for your search due to all the spying). I also rely a lot on Google reviews when I’m in a new place and just want to grab a coffee or a drink or something. Could probably use TripAdvisor for that though.
A lot of country- or city-specific subreddits either aren’t on here or are quite inactive. To be honest they were mostly cesspits on Reddit so maybe it’s no bad thing but you occasionally found useful information there.
Other than that, there were a few subreddits that were good for recipe ideas, like /r/EatCheapAndHealthy. /r/ZeroWaste was good too, on occasion.
In general, non-tech related communities don’t seem to have migrated over as much. Most of the subreddits I followed were related to technology in some way and now have pretty active communities on Lemmy.
I use a lot of free and open source software, and some of the stuff I use a lot I support with donations. Python, Mozilla, FairEmail are examples of software I have donated to. Wikipedia also.
