I use Safari all the time as well, but it doesn't behave very well with Reddit (keeps closing and reopening tabs due to "too much memory" problems. Other than that, it works for 99.9% of everything else.

Usually when sites get reloaded after sitting for a while due to “too much memory” it means the site has a memory leak (or several) that it’s owner has chosen to not address.

Annoying regardless, but arguably Safari is doing the right thing here.
