You might find the new editor is better now that it’s been live for awhile and had several updates. Depends on exactly what you are trying to do with it. If not, switching to self-hosted is not something you will regret as long as the hosting cost is marginal for you.
I set up a self-hosted blog years ago using this guide, and got used to the classic WordPress editor. So when they switched it I just installed the free Classic Editor plugin so I didn’t have to mess with learning the new editor. Overall it’s been a good experience.
The whole “freemium” model that WordPress.com uses can be pretty annoying at times. Better just to do self-hosted in my opinion. You can easily export an XML backup of your site from the dashboard and then import it into your new self-hosted install. You will then need to set-up a redirect for the domain name to point to your new hosting account, which WordPress.com charges for (surprise).
If you are truly staying in your house, and not going indoors anywhere with people from outside of your household (ordering grocery delivery, working from home, etc.) then I can see avoiding the vaccine until later, as you wouldn’t really be a risk to anyone else. But if you are still grocery shopping, or running any other errands inside or stores, then every time you do so you are putting everyone at some level risk.
On a related note, I find it strange that many of the groups hardest hit by COVID are also the groups least likely to get the vaccine. If anyone has any insight into why this is the case I would love to hear it.
