Again, because I'm boring like that: it's pretty hilarious to me that anyone would choose to make a new blog and not just use WordPress, especially when their stated aim contains this: "...that makes it as easy as possible to create posts". There are some moments when you shouldn't use WordPress. A blog is not one of those moments. Avoiding the obvious tool for the job is classic developer trendytool syndrome.
Not really, wordpress is a bit of nightmare to code upon and buying plugins and themes can result in incompatibility issues and vulnerabilities. I think Medium is easier, but it’s a walled platform.
And yes, this is what I do: maintaining 50+ sites for clients, so I have been round the block a few times, not just making this up.
