I used to have domain names and used another host for my web sites. When I started in 1998 it was very cheap some of it free but as the years rolled by it got more and more expensive.
I'd used Blogger since it started and over the years its configurability got better and better until now when I'm able to add CSS to a blog, I can make it look like a web site as easily as this one.
It's main advantage is being free, I'm not bothered about fancy templates people who come to my various sites don't either they just want the same as me information and the easiest way to present that is exactly the way Blogger works.
Access to all the editing tools is on one page and there is lots of help from Google itself, from YouTube and from countless generous people who kindly author lots of 'How to' pages.
Now every blog has an SSL certificate from its installation on Blogspot's web server which activates the padlock and the https protocol, allowing secure connections from a web server to a browser.
